More use of objects leads to performance problem?

Hello

I'm developing a game using MVC. In which I send several parameter to the addEventListener method. So I created a class customEvent with a parameter object type.

Here's the code flow

my custom event class:

public function CustomEvent (string:, customData:Object = null, bubbles: Boolean = false, cancelable: Boolean = false) {}

constructor

Super (type, Bubbles, cancelable);

this.customData = customData;

}

Adding listener

_myController.addEventListener (CustomEvent.UPDATE_MY_METHOD, doSomething);

function doSomething(myObj:Object){}

var param1 = myObj.param1;

var param2 = myObj.param2;

param3 var = myObj.param2;

}

To call my custom event.

var dispObj = new Object();

dispObj.param1 = "A";

dispObj.param2 = 100;

dispObj.param3 = 'PLAYER '.

dispatchEvent (new CustomEvent(CustomEvent.UPDATE_MY_METHOD, dispObj);

This idea makes me use more items in my game.

Now my doubt is, whether it will be led to memory leak or any other issue of performance? In this case can I replace object dictionary or any other better option.

Any suggestions? Please, I beg you.

Thanks in advance

It will not be a memory problem because these customevent get gc had. but there is more work for the flash player because there is more gc.

on the other hand, you have to use something to connect the necessary parameters so I don't see an advantage to the use of accessors get or other public functions which allows parameter values to retrieve.

Performance problem on the SQL query that does not use the primary key index
Hello!

I have some performance issues on a single SQL query (Oracle 10 g).
I could solve the problem by using the INDEX indicator, but I would like to know WHY this is happening.

* Tables *.
create table jobs)
ID number (5) not null,
name varchar2 (100),
primary key constraint Job_PK (id)
)
/
-Record count: 298

create table Comp)
integer ID not null,
name varchar2 (100),
primary key constraint Comp_PK (id)
)
/
-Record count: 193

-Relation m: n
create table JobComp)
integer ID not null,
id_job integer not null,
id_comp integer not null,
primary key constraint JobComp_PK (id),
unique key constraint JobComp_UK (id_job, id_comp),
Constraint JobComp_FK_Job foreign key (id_job) refers to Job (id),
Constraint JobComp_FK_Comp foreign key (id_comp) makes reference Comp (id)
)
/
create index JobComp_IX_Comp on JobComp (Cod_Comp)
/
create index JobComp_IX_Job on JobComp (Cod_Job)
/
-Record count: 6431

* Ask *.

When I run this query, the execution plan shows the index using (JobComp_PK and JobComp_IX_Comp).
No problem.

Select JobComp.*
of JobComp
Join jobs
on Job.id = JobComp.id_job
where JobComp.id_comp = 134
/
-runs in 0.20 sec

But when I add the field 'name' of the work table the plan uses full access table to the table of work

Select JobComp.*, Job.name
of JobComp
Join jobs
on Job.id = JobComp.id_job
where JobComp.id_comp = 134
/
-runs in the 2.70 dry

With the help of the index

Select / * + INDEX (Job Job_PK) * /.
JobComp.*, Job.name
of JobComp
Join jobs
on Job.id = JobComp.id_job
where JobComp.id_comp = 134
/
-runs in 0.20 sec

* Doubt *.

This behavior is correct?

PS. : I tried to recalculate the statistics, but nothing changes:

analyze the job calculation table statistics.
/
change the statistical calculation of index Job_PK reconstruction;
/
Start
dbms_utility.analyze_schema (sys_context ('userenv', 'current_schema'), 'CALCULATE');
end;
/

Hello.
I'm sorry for the plan unformatted.
The execution time of the querys "without field name' and 'with the field name with suspicion" are equal.
He has no problem caching, because I get the plans of the sequence different from the querys and repeated the performance. The result is always the same.

I don't think that there is no problem with oracle crossing LOOP IMBRIQUEE to the HASH JOIN when you include the field name and this should be the expected behavior. But it seems that your WORKING table has a degree of parallelism set against what is causing the query to run in parallel (as JOB table is now available with full table scan, instead of indexed access earlier). It could be that the parallel execution is contributor to extra Runtime.
(a) do you know why the degree of parallelism on the WORK table has been defined? Do you need it?

You can see if the following query provides a better response time?
```
select /*+ NOPARALLEL(JOB) */ JobComp.*, Job.Name
  from JobComp
  join Job
    on Job.id = JobComp.id_job
 where JobComp.id_comp = 134
```

Dear friend,

Why do you think you have problems with shared pool? In the ASH report you are provided, there was just 2.5 medium active sessions and 170 requests during this period, he is very low with swimming pool shared, problems
you have some queries that use literals, it will be better to replace literals with bind variable if possible, or you can set the init cursor_sharing parameter to force or similar, this is the dynamic parameter.
But it is not so dramatic problem in your case!

From ASHES of your report, we can see that top wait events is "CPU + wait for CPU", "RMAN backup & recovery i/o" and "log file sync" and 65% of your database of waiting time. And even in the background waiting events.
If I understand well report, you have two members in your redo log groups, you have problems with log IO writer speed, check the distribution of files on the disc, newspaper editor is slow causing it to wait for the other sessions. High
processor can be related to rman compression. Best service can we sea GATHER_STATS_JOB consumes 16% of activity 33% consumes rman and only 21% your applications and also there is something running
SQL * more under the sys (?) account. There is from the top of the sql page, this is the sql in your application, if I understand correctly, 'scattered db reading file' event indicates that full scans have a place, is it normal that your application? If Yes, then try using
running in parallel, as we can see in the section "Sessions running PQs Top" your report there is no running in parallel, but as I understand it there are 8 processors, try to use parallel executions or avoid full scans. But consider that
When you do full scans in parallel PGA memory not used CMS, then decrees setting pga_aggregate_target SGA and increase respectively.

Is there another application or a program running on the server except oracle?
Is the performance degradation was strong, I mean yesterday, everything was ok, but today all the evil, or it was good?

Check the reasons for the slow newspaper writer, it can greatly affect performance.
Also of 90% of the performance problems generally because of the poor sql, poor execution plans.
Also if you use automatic memory management, tap Settings, but you must know that in this case the settings will identify the minimum values, this is why define them to lower values in oracle can manage
entirely.
Don't increase your SGA at this stage, get the awr report, use @$ORACLE_HOME/rdbms/admin/awrrpt.sql, check your cover shot.

BUT first, you must change your backup strategy, look at my first post, after that check performance again, before you do that it will be very difficult to help you.

Good luck

WRT54GS - wireless performance problem

Dear someone

I am currently having performance problems with my WRT54GSv1.1

Just received my new internet connection to 30Mbit. Unfortunately, I am not able to download at that speed. If I connect via one of the linksys router's ethernet ports, I'm a happy person, but using the wireless makes me a little less happy.

Wireless: 15Mbit/s

Through the cable: 27Mbit/s

Network information:

The distance between the router and the computer laptop 3-4 meters

Linksys WRT54GSv1.1 - Firmware Version: v4.71.4

Network wireless - g only mode

TV - 6 (because all the surrounding neighbor use 10-11, I noticed using Cain Abel & wireless discovered 4.9.29)

Security: WPA2-Personal (TKIP + AES)

All other settings are default (just reset to the factory settings).

Laptop:

Windows Vista Business SP1 32-bit

Intel PRO/Wireless 3945ABG (installed the latest drivers from the website of intel, default settings)

When you check the diagnostic of Intel tools, it tells me the link is 54 megabits and pushes meter packages of 54 megabits, while all lower speeds remain the same.

More diagnostic information:

Percent missed beacons: 0

Percent transmit errors: 18

Current Tx power: ~ 32 mW (100%)

Supported power levels: 1.0 mW - 32.0 mW.

Hope someone can help me here.

Thanks in advance!

Kind regards

Ski Klesman

Although wireless g "connects" to 54 Mbit/s, the maximum possible wireless "data rate" (in ideal laboratory conditions) is only about 20 to 25 Mbit/s. Unfortunately, the phrase "in ideal laboratory conditions" generally excludes home intrusion!

The aerial transmission for wireless connections is higher than for wired connections. Thus, most individuals find that their Wi - Fi connection works at 50% to 70% of their speed of wired (LAN). Your wired LAN being 27 Mbps connection speed, your 15 Mbps wireless speed is within normal limits.

You might be able to tweak a bit more speed from your wireless network by optimizing all your wireless settings. Here are a few suggestions:

I guess you want actually to WPA2 encryption. If so, set to AES only. When you set the router to TKIP and AES, you actually tell the router to accept a WPA or WPA2 connection.

Also, give your network a unique SSID. Do not use "linksys". If you use "linksys", you can try to connect the router to your neighbor. Also set 'SSID Broadcast' to 'active '. This will help your computer to find and lock on the signal from your router.

Bad wireless connections are often caused by interference from other 2.4 GHz devices. This includes cordless phones, baby monitor wireless, microwave ovens, wireless mice and keyboards, wireless speakers and wireless network from your neighbor. In rare cases, Bluetooth devices can interfere. Even some 5 + GHz phones also use the 2.4 Ghz band. disconnect these devices and see if that solves your problem.

In your router, try another channel. There are 11 channels in the band of 2.4 GHz channel 1, 6 or 11 generally works better. Discover your neighbors and see what channel they use. Because the channels overlap, try to stay at least + 5 or - 5 channels of your more powerful neighbors. For example, if you have a powerful neighbour on channel 9, try any channel 1 to 4.

Also, try putting the router about 4 to 6 feet above the ground in an open area. Do not place behind your screen or other computer equipment or speakers. The antenna must be vertical.

In addition, in the computer, go to your wireless software and go to 'Favorite networks' (sometimes called 'Profiles'). There are probably a few listed networks. Remove any network called "linksys". Also remove any network that you don't recognize or that you no longer use. If your current network is not listed, enter its information (SSID, encryption (if any) and key (if any)). Select your current network and make your network by default, then set it to auto login. You may need to go to 'settings' to do this, or you may need to right click on your network and select 'Properties' or 'settings '.

If you continue to have problems, try the following:

For wireless g routers, try setting the "baud rate" at 54 Mbps.

If you still have problems, download and install the latest firmware for your router. After an update of the firmware, you must reset the default router, and then configure the router again from scratch. If you have saved a router configuration file, DO NOT use it.

I hope this helps.

How to use memory and boost system performance by using 8 gb win7 Professional 64-bit

Hello

I m using HP430 (I have 3 Basic) laptop with win7 64 bit Professional installed.

recently, I ve upgraded to 8 GB of ram, but I don't really see the system performance problem.

Can anyone guide the optimal memory use and improve the performance of the system (file e.g.page, etc.)

Thanks in advance,

Prashant

Hello.

If, for example, your system was using 2 GB before you upgrade the memory, it will use more than 2 GB. The only time where you would see that a performance gain would be if you had only 1 GB in the system and the system was attempting to use 2 GB. If you had more that what you were using in the first place you will see no difference. 8 gb is a lot of memory for normal use. At most I use about 3.5 GB and it is with some powerful applications running.

See you soon.

4.2 APEX performance problem

Hi all

We are facing the problem of performance when we are by selecting one of the underside of responsibility that rests in the Organization as if we select APEX_01 Reporting ALL then in this case, we can see all the organization such as ETL, BRN, CHICKEN ect in home page, but I am facing performance problem when it forms that select area of responsibility to the home page. Please indicate how to check this page's performance in the APEX and also advise how to solve this problem.

HP Pavilion 15-n005sg: performance problems and worsens

Hello

I bought this PC here is a year, has been a very good PC with good performance, but has been doing more and more slow to the month, for example, I used to run Diablo 3 on average - high specification with 60 fps constant with no performance problems, but that in the end, I can't still running at ultra low care without screen freezes and fps drops to 1-2 as well as the League of legends and other games.

It takes more and more time for my pc to turn on, which was like 30 ~ 40 seconds not takes like 3 minutes.

the performance gets really bad and should not happen on a pc of 1 year.

What can I do?

An update of the system may be your best course of action.

Your data, files, etc. will be retained. Any Windows apps store is kept.

Any program that came pre-installed is preserved.

BUT all programs which are not in the above categories will have to be resettled; your games, printer, etc.

Performance problems on Oracle 11 G with Windows 2008 64 bit.
Hello world

I noticed that our database is going bad and low every week. My server has 16 GB of RAM and 10 GB are dedicated to the database Oracle, it is a 11.2.0.1 with Windows 2008 R2 SP1 64 bit. I would like to know according to the values of the movement following you guys recommend to adjust in the init.ora:

ORCL.__db_cache_size = 5402263552
ORCL.__java_pool_size = 33554432
ORCL.__large_pool_size = 33554432
ORCL.__pga_aggregate_target = 3657433088
ORCL.__sga_target = 6878658560
ORCL.__shared_io_pool_size = 0
ORCL.__shared_pool_size = 1308622848
ORCL.__streams_pool_size = 33554432

* .memory_target = 10511974400
* .open_cursors = 5000

* .optimizer_mode = "RULE".
* runoff = 300

According to the target memory on how values can be increased the process, pga_agregate_target, etc.

We also have problems with the bug Bug 9593134 "connection to Oracle 11 g are slow and can take anywhere from 10 seconds to 2 minutes." there is a difficulty on linux by removing dns names on this subject, but someone has experience on windows platforms?

Thanks to all and sorry for my English.

Kind regards.

Arturo.
Concerning the long connection times, have you tried to use the network (such as Wireshark) packet capture software to determine that the client computer when a connection attempt is initiated?

The Oracle database time can help the model statistics and wait events extensive system you diagnose performance problems related to poor (you should not only look at the statistics, but rather capture the current values, wait a while, statistics capture again and compare the evolution of the values of the statistics). A statspack report may also help - but a trace 10046 to level 8 or 12 is more appropriate if you are able to identify a few sessions that have performance problems.

I claim not just blindly changing the settings, even if I'm curious about:
* Why the session level setting OPEN_CURSORS is set to 5000 - you expect a single session to hold cursors open 5,000?
* Why do you use the obsolete RULE based optimizer?
* Why the MEMORY_TARGET parameter is used when the target SGA_TARGET and PGA_AGGREGATE are specified?

AE CS6 performance problem

I have an eccentric performance issue that I am looking for help on. I found this in AE CS5, and it's still in AE CS6, so I thought I should sue here. It is on a platform of win7. For the record, everything is fully updated and patched, including display drivers.
First of all, a context. Most of my work is interviews and classes, for the most part two cameras. Most of the interviews are one-man-band with me handling everything. A few times, I had to film in conditions of low light, resulting in a noisy capture one or two cameras. Both cameras are capture in AVCHD 1080 p 30. When we are lucky, we get one interviewee who is hinged, and has much to say, these clips can be long for long minutes. If we were talking about a second clip seven here I won't be wasting your precious time. I'm talking as much as 25 minutes of film.
What I've done so far, is send the noisy images of the body to AE via dynamic links and run the effect of "reducing grain. This isn't a problem of editing - I just disable the effect in AE so it does not interfere. But when it comes to export, a few seconds of these sequences is painful and a few minutes is ridiculous. I had one piece of 3.5 minutes take 16 hours to export, or right to 10.25 seconds for each image.
Naturally, I ran win7 Task Manager / resource monitor to see what was going on. What I've found, is that the machine was not limited - I couldn't find a bottleneck. It's a nuclei of i7 930 machine, so four eight hyper-threads. Everything works in about 20-30% in this case. I got 12 GB memory and had as much as 6 GB free. I have three hard drives and none of them were busy - the target drive, getting a continuous line of images in Scripture, but of it is average queue length was zero. The system was written only about 2 MB per second. Like I said, without bottlenecks. So, what's the problem?
I have since tried to isolate the problem. Using this same sequence, if I have AE make internal make the queue, she turns on the machine - all Hyperthreaded running hard (85-100%), all of the memory used and target the disc is hammered. 10.25 sec/frame to 1fps, it goes 10 times faster. But if I made the same images through the Media Encoder, I'm back for a very slow rendering.
It seems that when EI is called through hotlinks, it runs only on a single hyper-thread. And when AE must touch each image (as it does in using an effect of "reducing grain"), he actually makes a hyper-threaded machine eight in one hyper-thread machine. Why is this? What can I do about it?
I can't find the settings for this effect in some way. I played with memory and multiprocessing preferences without success (my best settings to aid internal queue of EI turned out be book 4 GB memory for other processes and turn on the simultaneous rendering of multiple images with the allocation of RAM / CPU at 1.5 GB resulting 4 hyper-fils used for this background). Y at - it the parameters for this effect?
In summary, if I turn off the grain effect to reduce in AE and the export of the body, the machine blazes far and finished my export of 3.5 minutes in about 35 minutes. If I turn on the effect of grain reduction, it takes more than 16 hours to do the exact same job. If I turn just 3.5 minutes of the camera which needs the grain effect to reduce, with ME directly (taking the body of the equation), it takes the same 16 + hours.
So I think that it is a performance problem with AE and how it works with dynamic linking.
Certainly I'm not the first person to see it. So, I hope that there is good workaround solutions. I don't want to make an intermediate AE file if there are good alternatives. This is a workflow that dynamic binding was supposed to eliminate. In addition, I want to avoid re - compress these files, and I don't have the disk space to make an intermediate file lossless image I (even a CODEC moderately compressed as Cineform generates more of 10 x).
Suggestions? Please?

Nothing to correct because nothing is broken. Read it here at the end down.

SEM_MATCH queries performance problems
Hello

We run into performance problems when you use queries SEM_MATCH.

We have a model for data (ABox) containing a triple 12 000 000.
We have a model for the plan (TBox) containing 800 triple.
We ran an implication of "OWLprime" and built the model and entailment index with the SEM_APIS commands.

The number of triplets after the execution of entailment was 35.000.000 triples.

We use the following hardware configuration:
OS: Windows Server 2008
CPU: Intel CPU Xeon X 5460 @3.15 GHz (2 CPUs).
64-bit operating system.
Memory: 32 GB

The results below, it seems that whenever we execute a query against the index of inference, execution time increases significantly.

Here are the results:

Doron
If you use 11.1.0.7.0 and you have installed the 7600122 hotfix, please use:
-Brace for the SEM_MATCH query syntax
-Virtual model (using SEM_Models ('TOM_ONTOLOGY', 'TOM_ONTOLOGY_TA'),
SDO_RDF_RULEBASES ('OWLPrime'))
-ALLOW_DUP = T (as part of the parameter options of SEM_MATCH)

On query performance problem. Need help.
It is essentially a performance problem. I hope someone can help me with that.

Basically, I have four old masters (150000 records), (100000 records) Child1, Child2 (50 million records!), child 3 (10000 + records)
(please forgive the alias).

Each record in the master has now more than one matching record in each table child (one to many).
Also there may be any record in any or all of the tables for a particular master record.

Now, I need to get the maximum of last_updated_date for each master record in each table 3 child and then find the maximum of
the three obtained last_active_dates from the 3 tables.
for example: Master ID 100, to interrogate Child1 for all Master ID 100 records and get the max last_updated_date.
Same for the other 2 tables and get the most out of these three values.
(I also need to deal with cases where no trace may be found in a child table to a Master ID)

Write a procedure that uses sliders that the value of each of the performance hits of child table
evil. And that's, I need to know the last_updated_date for each master file (all 150000 of them). It will probably take days to do this.

SELECT MAX (C1. LAST_UPDATED_DATE)
MAX (C2. LAST_UPDATED_DATE)
MAX (C3. LAST_UPDATED_DATE)
OF CHILD1 C1
CHILD2 C2
CHILD3 C3
WHERE C1. MASTER_ID = 100
OR C2. MASTER_ID = 100
OR C3. MASTER_ID = 100

I tried the above, but I got an error in tablespace temp. I don't think that the application is good enough at all.
(The GOLD clause is to take care of any records in a child table. If there is an AND, then the join and then select
No, not even if there is no record in a child table, but valid values in the other 2 tables).

Thank you very much.

Published by: user773489 on December 16, 2008 11:49
You want alias to this field then.
```
SELECT MAX (C.LAST_UPDATED_DATE)
FROM
(select child1_master_id MASTER_ID, field2, field3,... field4 from CHILD1 UNION ALL
 select child2_master_id MASTER_ID, field2, field3,... field4 from CHILD2 UNION ALL
 select child3_master_id MASTER_ID, field2, field3,... field4 from CHILD3) C
WHERE C.MASTER_ID = 100
```
If do you something like that, and explicitly list the columns you want.

Edit: for something like a specific query for a MASTER_ID...
```
SELECT MAX (C.LAST_UPDATED_DATE)
FROM
(select child1_master_id MASTER_ID, LAST_UPDATED_DATE from CHILD1 where child1_master_id = 100 UNION ALL
 select child2_master_id MASTER_ID, LAST_UPDATED_DATE from CHILD2 where child2_master_id = 100 UNION ALL
 select child3_master_id MASTER_ID, LAST_UPDATED_DATE from CHILD3 where child3_master_id = 100) C
WHERE C.MASTER_ID = 100
```
That should give you very good performance by raising a record. But a better idea, as indicated, would be to get it all at once with a sql:
```
SELECT MASTER_ID, MAX(C.LAST_UPDATED_DATE)
FROM
(select child1_master_id MASTER_ID, LAST_UPDATED_DATE from CHILD1 UNION ALL
 select child2_master_id MASTER_ID, LAST_UPDATED_DATE from CHILD2 UNION ALL
 select child3_master_id MASTER_ID, LAST_UPDATED_DATE from CHILD3 ) C
GROUP BY MASTER_ID
```
This will give you the max for each MASTER_ID in a sql without a cursor.

Satellite Pro A120 - more useful manual

These loans and able to support, I would like to ask is not to be put off by the naïve questions.

I'm doctor in mathematics who has always had the help of a COMPUTER team and has never had the responsibility of a technical problem. This time I had to deal with a malfunction of the CD/DVD, with my manual, your help and everything I could find on the Internet.

When I came to the conclusion that my only alternative was to order a reader of CD from the manufacturer, delays, a response to persuade them to list all the controls and the tests proposed by you all, organize them in a logical order and apply them. Now, I have a job perfectly DVD/CD player.

I would like to get a manual more useful that will allow me to open the laptop, if so, any suggestions?

Hey Buddy,

To be honest I don t understand your question exactly. You wrote that you have a working perfectly CD/DVD player then why you need a more useful manual?

These technical manuals that you mean that they explain how to disassemble a laptop are not for the public. Only the manual can be downloaded, other manuals are available to the service providers allowed according to me.

In addition, in your user manual, you can find a list of supported CD/DVD players. This should be useful!

my account is taken hostage can not enter in more & used for fraud by the pirate air
