• Qosmio X 305 Q708 serious performance issue

  Hello, everyone. I have a serious problem with this laptop. I think this laptop has been so powerful that it could work almost all the games with high detail settings. But yesterday I installed Street Fighter 4 and red alert 3. The display with the max settings, the game wasn't at all flowing. However, these two games don't ask extrem powerful processor and graphics card. That's why I don't understand why with like a powerful laptop, two games work properly with the display in the game settings. (Street fighter max settings: 30 frames per second.) RA3 maximum setting: I don't know, but really slow).

  Also, when I run the Benchmark in street fighter 4, the reference said, I am with a Nvidia Geforce M9400G. So I wonder if the towing 9800GTS in SLI Nvidia are enabled. However, I put the laptop in Boost Performance mode and I can't find no choice to activate the chart of GTS 9800 cards in SLI mode.

  So could someone tell me how can I activate 2 Geforce 9800GTS SLI graphics card or explain to me why it is so slow when I run a red alert 3 and Street Fighter 4 with the display max settings.

  (Reminder: the operating system is Vista Ultimate 64-bit.)

  Hey,.

  Generally speaking, it is important to use the latest drivers to display by Toshiba. This means that these drivers are pre-tested and will definitely work on your X 300. So it s a good idea to install only those drivers.

  I put t that s is exactly your problem, but also make sure that the latest version of DirectX is installed. You can download the latest on the Microsoft Web site.

  As far as I know in Windows in energy saving mode, the graphics card is going to be underclockee to save energy (Geforce 9400). If you activate the mode performance, connect the AC adapter, the card is recognised as the 9800M GTS as usual.

• Smartphone blackBerry Storm performance issues (and suggestions)

  I want to start and say that I don't like my phone.  When it works (which is most of the time), it works fine.

  But there are certainly problems of software.  As a software engineer, the OS has some memory serious management problems.  This seems to cause most of the problems I'm having with the phone.  I'm running the latest Verizon S/W (v4.7.0.148).

  Problem #1:

  I am a paranoid person.  There are a lot of personal information on my phone, I have currently international calls helped that I need this feature.  So to protect me my phone is locked when it is the case or after a period of inactivity time.  It is a good practice.  Part of the draw to the fate of the Blackberry is the security that you can configure on the device (I'm not paranoid enough to allow all the protections of encryption - yet).  Problem of the storm is that it can take 1 to 5 minutes to get the phone unlocked when unholstering.  It is not an exaggeration.  As the performance of the memory gets worse, time takes more time.  If I had to make an emergency call, it could be the difference between life and death.  5 minutes is a long time to wait to call 911.  This must be corrected!

  Problem #2:

  The phone must be "reset" once a day to remember "lost."  It is just poor programming.  I don't know if this problem of BB OS or Apps I'm running, but in both cases, this isn't fair.  After the reboot if I go to the display of memory under options I could have about 3-5 MB of free memory.  After a few hours of use, this will almost always '0 '.  I installed MemoryUp Pro, which seems to have extended the period of time between the battery grips, but I still don't think we should ask all owners of BB Storm to pull there battery once a day.  The other answer I get is "do not run so many Apps.  I get all my applications when finished.  Are the only ones that I continue to turn: Blackberry Messenger, Yahoo Messenger, Google Talk and Google Maps (Latitude).  Other applications running, you can't get out (phone, browser).  I tried doesn't work is not the 'optional' tricks and performance has not really much better.

  Problem #3:

  Missed calls.  This is probably related to problems of memory above, but if the storm can be used as a phone, then I should buy something else.  Although the occurrence of this problem has gone down because I installed MemoryUp Pro and perform the reset once a day, sometimes still about 1 to 5 times.  It takes so long for the phone to 'wake up' when a call comes in (especially if it is holstered), at the time where I hit "Answer", a call has been Messaging voice or even worse, the phone doesn't ring at all.  All I get is a notification of appeal lacks the 'unknown number '.

  Problem #4:

  Battery performance could be improved.  The battery that comes with the storm has about 24 hours on 24 with the Radio and Bluetooth.  Really, this isn't a problem if you know it.  I solved the problem by buying a 2700 mAh battery for extended life of BoxWave I use when traveling.  Makes the storm bit bulky, it will give me 2-3 days of life.  I don't know how this could be improved if not

  I hope that the developers of RIM are trying to solve some of these performance issues.  Certain tasks should be a higher priority as they seem to have (like phone & Unlock).

• Management performance issues and huge catalog

  I shoot architecture and real estate. I turn every day hundreds of frames and my current catalog becomes huge. I'm also starting to see a huge performance hit recently. Last night I just changed until 03:30 because LR would take some time as 20 seconds to perform a single task (like changing a slide or photo of the flag). A lot of time spinning beach ball. I have an external hard drive which I support to locally.

  What I was wondering is if I have everything except the most recent project files copy the disk external then keep it unplugged when I WIP edition if it would help performance issues?

  MacBook Pro (10.9.5) and LR CC running. I optimized my catalog and I also have a Cocktail for Mac running on my system to clean the memory, etc.

  Other ideas of huge catalogs management would be useful. I prefer not to make a new catalog for each customer that I shoot several each day and passing backward between catalog every day would be a pain in the thigh.

  Hi KristianWalker,

  Have you tried to increase/purge your Cache? See How to improve and accelerate the performance of Photoshop Lightroom for more ways to optimize Lightroom.

  Also what size is your catalog at the moment?

• performance issues and connectivity at random

  Hi all, I have a new rn204 I have some problems with.

  my current setup is:
  ReadyNAS 204 6.5.1
  3 x red new WD 3 to x-raid 25% free
  1 x 1 GB link to router (asus rtn66u)

  the first issue I see is intermittent from speed in transfer large files. Normal performace is about 110 MB/s, which is to saturate the line but I saw at random speeds fall at 100 kb/s

  2nd edition: ping the IP address of the nas are often 50%, 75%, 100% of loss on 4 pings. most of the time it's good, but sometimes not.
  3rd edition: the nas has been itself reassign to an ip at random in the range 169.254.x.x 192.161.57 about once per day, I configured for a static ip address but conectivity will die (can't ping and the router can not see) every day or almost.

  usually the problems disappear if I pull (good quality cat6) ethernet cable in the back and reconnect it.
  Sometimes this also pushed (or worse) transfer speeds if they are slow.

  pls send help!

• Performance issues and options to reduce the loading with the Oracle text implementation

  Hi Experts,

  My database on Oracle 11.2.0.2 on Linux. We have Oracle implemented for the fuzzy search. Our oracle text indexes are defined as sync on commit that we cannot afford to have stale data.  Now our application done literally thousands of inserts/modifications/deletions of these columns where we have these Oracle text index defined. Thus, we see a significant impact on performance because the oracle text synchronization routines is called on each commit. We do nightly index optimization (optimization full every night at 3:00).  The text index oracle internal operations are appearing at the top of the sql page in our AWR report and fears it causes a lot of load on the DB.  Since we do optimization of the complete index once during the night, I think I should change that, and if I do, he's going to help us?

  For example, here are some data of AWR report my one day:

  Time elapsed (s)	Executions	Time by Exec (s)	% Total	% CPU	%IO	SQL ID	SQL module	SQL text
  27,386.25	305 441	0.09	16.50	15.82	9.98	ddr8uck5s5kp3		Start ctxsys.drvdml.com_sync_i...
  14,618.81	213 980	0.07	8.81	8.39	27.79	02yb6k216ntqf		begin ctxsys.syncrn (: idxownid,...)

  
  More top sql full text:

  ddr8uck5s5kp3	begin ctxsys.drvdml.com_sync_index (: idxname,: idxmem,: partname); end
  02yb6k216ntqf	begin ctxsys.syncrn (: idxownid,: idxoname,: idxid,: ixpid,: rtabnm,: flg); end;

  Now if I do optimization of the complete index that more often, and not only once night 15:00 will be this average, the load on DB sync on commit will decrease? If Yes, how many times should I optimized and the optimization itself does not lead to a load? Can anyone suggest?

  Thank you

  OrauserN

  It's to you which values you want to experiment.  Since 1 G, which is the same as 1024M is the maximum I could try that assigning to an index and see what effect it has.  You can use the same AWR report that you used previously and compare performance.  To determine when paging depends on your operating system and what tools you have.  Another option might be to use TRANSACTIONAL, that allows searching for unsynchronized lines and allow you to synchronize every five minutes, like Herald suggested, without any latency problem.  You can read about it here (scroll down to transaction):

• HP Elitebook 8570p - Windows XP USB very slow and the transfer rate performance issues.

  Hello. I was wondering if anyone else knows some performance issues with the HP Elitebook 8570p and Windows XP Pro - SP3.

  I get a VERY slow start, general poor performance (waiting time when opening files and programs).

  I asked to burn in tests that show that everything is good.

  USB transfer rates are VERY slow (tried all ports of a Seagate FreeAgent USB drive, which works fine on other laptops etc.) for example a 30-minute transfer a 7gig single file of the USB HD on the desktop. Only 3 minutes to do the same on another laptop.

  I think there are problems with the drivers, like Windows 7 works very well and does boot from a bootable USB.

  USB transfer rate are also good when starting from a Windows boot environment.

  I installed HP SoftPaq Download Manager, and all the drivers are up to date.

  Hello:

  I think outside of the box here... Select the Intel (r) 7 Series Chipset Family SATA AHCI Controller instead.

  If it does not, I raise the white flag.

• Untangled RoboSource slow performance issues

  Hi all
  
  I'm a noob-Robo (noobie, novice, etc.) but not new computers and databases and others. We have a team of 5 authors are all working on separate projects but under even version RoboSource Control. We know some questions serious performance: projects can take over an hour to check outside or inside. not all users can see projects; "Rename" do not get rid of the old actually prefer a copy under the new name (?); etc.
  
  I'm trying to 'normal' basic behavior for RoboSource Control as well as some best practices for multiple users. I wonder if there is something more in depth to describe the RoboSource Control engine and possibly maintenance tasks to help what seems to be a jumble of nodes that are not all necessary, too many users "admin", etc. I expect that the "cleansing" will solve many of our problems.
  
  So, rather than go in each problem in the forum, I prefer to find the right resource and to tackle this thing by iteration.
  
  Thanks for your useful suggestions
  
  Don

  I wanted to update the forum about this performance issue. After further investigation, we note that serving PC server worked for 6 months without interruption. In addition, she has 512 MB of RAM, but the ROBOSOURCECONTROL service consumed 350 MB of it. The rest of the system resources were probably permutation are busy. A reboot which is brightened and RSC performance is splendid - from 30 to 60 minutes, until about 15 seconds for a GET or a check-in.
  We suspect there is a memory leak in CSS, but I can start a separate thread for some tips on how to identify and report a bug for this package.

• Procedure of ODI with slow performance (SOURCE and TARGET are different Oracle databases)

  Hi experts,

  I have an ODI procedure but its market with slow performance (SOURCE and TARGET are different Oracle databases), you can see below.

  My question is:

  It is possible write Oracle BULK COLLECT at the 'command on the target' (below)? or

  There is a KM of ODI that perform this task below in a quick way? If so, what KM can you guys suggest me?

  I found 'Oracle Append (DBLINK) control' but I try to avoid creating the dblink database.

  ===============================================================================

  * COMMAND ON the SOURCE (* technology: ORACLE * logic diagram: ORACLE_DB_SOURCE):

  SELECT NUM_AGENCIA, NUM_CPF_CNPJ, NOM_PESSOA

  < % = OdiRef.getSchemaName ("D") % >. < % = odiRef.getOption ("P_TABELA") % >

  ===============================================================================

  *ON the COMMAND TARGET (* technology: ORACLE * logic diagram: ORACLE_DB_TARGET):

  BEGIN

  INSERT INTO DISTSOB_OWNER. DISTSOB_PESSOA (NOM_PESSOA, NUM_CPF_CNPJ, FLG_ATIVO)

  VALUES ('#NOM_PESSOA', '#NUM_CPF_CNPJ', THE FROM ');

  EXCEPTION WHEN DUP_VAL_ON_INDEX THEN

  NULL;

  END;

  Thank you guys!
  

  Please use SQL for SQL command Append KM... You can delete the unnecessary steps in the KM.E.g. fi you won't create I$ table, control flow etc, then you can remove related steps.

  Please try with that.

• conflict of SCSI reservations and VM performance issue

  In my project, I met a situation like several machines virtual performance deteriorated suddenly.

  I checked the logs vmkernel which shows

  WARNING: SCSI: 119: default i/o because of too many conflicts of booking

  WARNING: FS3: 4866: booking error: SCSI reservation conflict

  My theoretical knowledge, scsi reservation conflicts will lead to a disappearance of the store of data/Lun. But here, in my case, no data store is missing.

  I checked all esx hosts (in a cluster) who share the same data warehouses.

  I was checking for the store of data/lun is locked by a specific host.

  Expecting to be reservations pending... 1

  esxcfg-Info | egrep-B5's Reserved. Output of the command on hold. "

  But in all the reservations pending hosts is showing ' 0 'but not ' 1'.

  Even if I reset all the LUNS to an ESX Server with the command.

  vmkfstools - lock lunreset /vmfs/devices/disks/vml.xxxxxxx

  I have a lot of questions in my mind for the situation described above. I will ask you a bit.

  1. reservations of Scsi conflict cause one

  a missing data store

  degradation of the b.performance for virtual machines

  c a or b

  d. a and b

  2. What are the steps we take when we identify on the ESX Servers scsi reservation conflict?

  3. where we can find good documentation on the reserves of scsi?

  4. can you suggest a document on performance of VM problems troubleshooting?

• New installed SSD and performance issues

  Hi all!

  I just reinstalled my computer with a new X 25 - V Intel SATA SSD disk 40 GB on which I have installed only, Win7 and CS5, and with my processor i7980x and 24 GB of ram, I was expecting a few performance super crazy (my number of Windows performance is 7.7 to 7.9 possible) and... my Premiere Pro is now painfully slow... Everything is fine in the computer...

  Look at a real-time video, when not returned, is impossible or extremely pixelated (it was fine before with my HARD drive).

  Any help is welcome!

  Thank you

  Etienne

  SSD make great records of program/OS, but they may be quite low for CS5, especially at the price/generation X 25-V series of Intel. As to why SSDS are poor for CS5, there is a problem with slow performance in writing.

  Put everything on your hard drive unless "media DB cache" (CS5 projects, media, cache of media output, etc) and you should be fine. BTW, you have a powerful processor and plenty of RAM, so your material would be much better balanced if you were to use a total of 4 disks 7200 RPM SATA: 2 in RAID 0 for projects and media; 2 in RAID 0 for the media in cache and make out. Check out the 'material' forum for a lot of discussion material.

• Slow freezing issue and Satellite A200 - 1 M 7

  Dear Sirs,

  I have Toshiba A200 - 1 M 7 & since I bought it I got a problem which is cold and starting to take too!

  It took me so that it starts about 10 minutes and sometimes when using my laptop, the HARD drive light turns off and my computer laptop it stops!

  It s and also it's so slow!
  I don't know why this happens, but I sent it to the dealer and he told me that there is a problem with the hardware!

  Recently, I'm using Linux! And nothing happens with me!
  I mean everything is going normal & without freezing and so fast!

  So I think that the problem with Windows Vista.
  So could you please help me, if someone faced this problem before?

  Agress
  Ferriol Allaou

  Do you know why your A200 is slow and boots slowly?
  Because Vista needs for more resources as a Linux OS or OS to win at the beginning.
  In addition Satellite charge you a large number of background at startup process.
  This slows down the laptop and a longer startup time.

  Background processes belong to some Toshiba and other tools that are needed to use and control the functionality of any computer laptop,

  But of course you can disable it if you wish;
  Run msconfig and Sartup tab you could disable some unnecessary applications (for you).

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system. For
  each driver in the list, additional useful information is displayed: load address of the driver, description,.
  version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
  video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
  cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
  This will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
  own the software and drivers and all other main drivers that you have.

  Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
  (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
  updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.

  Always check in the Device Manager - tab drivers version you install actually shows up. This
  because some restore drivers before the most recent is installed (particularly that audio drivers) so install a
  pilot - reboot - check that it is installed and repeat if necessary.

  Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

• Performance issues with large number of nodes

  I am creating an application to display graphics (large), for example:

  

  But I ran into some performance issues, even for a relatively small number of nodes in the scene graph (+-2000 in the picture above). The graph is built, step by step, adding circles and paths to a StackPane. Circles and paths can be semi-transparant. For a small number of nodes, I get a solid 60 FPS, but this decreases over time to about 5 frames per second. As soon as I stop adding new nodes, the framerate shoot again up to 60 images per second. The framerate drop even when all the nodes are outside the viewport.

  My questions are:

  * Is Platform.runLater () call to 2000 times a minute too?

  * This might just be a problem with my graphics card? (I have an Intel HD Graphics 3000)
  * JavaFX pulse recorder says such things, are there meaningful information in that I'm missing?

  Basically, try some optimization of performance ranging from the simple to the complex.   Each of the changes below may provide you with an increase in performance.  Some will probably increase performance much more that others (depending on where is the real bottleneck).  I would probably start by replace the paths to the lines and reduce the number of Platform.runLater calls (as adding nodes that fall within the viewport can be difficult only).

  > The framerate drop even when all the nodes are outside the viewport.

  Place the nodes in the graph, which fall inside the viewport.

  > Is Platform.runLater () call to 2000 times a minute too?

  Yes, there is no reason to call it more than 60 times a minute when the framerate of JavaFX is capped at 60 frames per second by default.

  > This might just be a problem with my graphics card? (I have an Intel HD Graphics 3000)

  Yes, it's a graphics system relatively low-end.  But, look at the comment of developer below - your CPU and choice of graphic primitives can also affect rendering speed.

  > Adding circles and the paths to a StackPane

  You don't need a StackPane to this, a group is a container easier and probably better.

  > may be semi-transparant

  Remove transparency * may * cause acceleration.

  https://JavaFX-JIRA.Kenai.com/browse/RT-20405 : improve the rendering of path performance

  Maybe if you use lines rather than the paths, performance might improve.

  A comment by a developer on this performance tweak application is:

  «It is quite normal for applications that use arbitrary paths (if the node path objects, SVGPath, polyline, or polygon) because these paths are rendered in software.» As card circle, Ellipse, line and Rectangle very primitive forms easily to the operations that can be performed entirely on the GPU, which makes them essentially cheap. There is no need to compare the rendering of a complicated shape for rendering of simple primitives for this reason. »

  Setting the cache indicators can help, but probably only if you animate nodes.

  ----

  Present level of detail of your graph functionality so a chart with zoom out is not make as many nodes as a part of zoomed in.

  ----

  You run any code important calculation on the JavaFX application thread that could stall it?

  Can make you available a ftom so that others can reproduce your problems?
