  Hello

  There are a few things you can do to make the system more fast/more attentive.

  Be careful that a lot of these programs and services really needs to run and often remove some

  Another thing that helps performance is updated drivers - Vista like the updated drivers.

  This is my generic how updates of appropriate driver:

  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.

  This leaves ONE of Windows updates, but it will not install the drivers who are generally older and cause
  questions. If updates offers a new driver and then hide it (right click on it) and then go look for new ones
  manually if you wish.

  ReadyBoost can help, more RAM, and ReadyBoost is even better and RAM is pretty cheap these days.

  The max supported in Vista readyboost drive is 4 GB - if you get a larger drive 4 GB you can use the
  rest for storage.

  You need a very fast car and pay little attention to the demands of the manufacturers that they are ready for ReadyBoost as
  even some slow readers claim that.

  From our point of view, it would be ok if latency increases when you increase the load with multiple virtual machines. But as already out doubled over our cluster becomes broken after increasing the number of virtual machines at some point.

  We are currently testing with a subset of four nodes VSAN with the above config. In this group, we were able to turn on 187 load generation machines before that three of the four hosts entered the State "is not responding.

  We wonder if anyone has also made large performance tests. If so, we would be very interested in comments you make. Maybe this helps us to find the fault of our construction.

  Kind regards

  Daniel

  With the help of VMware we discover that the problems we face are caused by virtual machines gen load... each vm is generating 2048 ios in circulation... so with 187 VM on the cluster, we unreal ios in circulation (382976... when I remember the graphic observation of our cluster it would reduce up to 13000 per host) which we will never see in real world scenarios. With this high traffic vsan 6.1 ios has problems and vmware is working on a solution... maybe with 6.2 and qos that is resolved?

  A few other changes:

  -a newer driver for our network cards intel x 710

  -new driver and firmware (beta version of dell) for our h730 perc controller

  and some advanced settings:

  esxcfg-advcfg - 100000/LSOM/diskIoTimeout s

  esxcfg-advcfg - s 4/LSOM/diskIoRetryFactor

  esxcfg-advcfg - s LSOM/2047/heapSize (with these parameters, we were able to create 3 starts - with 7 metal discs and 1 flash device - for each host)

• OSB: Performance tests

  Hi all

  I want to test our Service OSB for Performance. I already did the test in SOAPUI. But my test performance requirement is something like below

  Request and the response stream :

  The client sends requests to

  • OSB of level of consumption (this enrichs the message) and for the Orchestration level OSB
  • OSB level orchestration (Orchestration done) by contacting OSB data layer
  • Data layer OSB (it connects to the database of the provider)

  I would like to send a request from a performance tool that could give me the amount of time needed to each layer of OSB.

  Please help me!

  Thank you

  Provide a follow-up on each of the OSB services involved in the flow. You can turn on tracing to the level of service, level of pipeline or action. Then run your SOAP UI or Load Runner or jMeter performance test.

  After that, you can monitor the statistics for each of the services in the health section for the sbconsole of the dash service. Depending on the chosen level you will be able to see the number of applications, the average processing time, min and max processing time for each service/operation/pipeline/action etc.

• Performance tests: bind variables

  When you write a SQL for the application, I want to do some performance testing of SQL before providing to JAVA developers. I understand that I need to test using bind variables, can someone guide me how do? What are the best tools out there to achieve? Please provide some guidance. Thank you!

  Rinne says:
  I read more about bind variable and I can test the use of bind variables. I understand that testing SQL using bind variables is a closer representation of the real world. Even when queries have large tables, the performance would be similar if I run the query using literals twice (to avoid hard analysis) compared to tests with bind variables? I am trying to understand more thoroughly the need for tests with bind variables. Why we take more time than the other? Thank you!

  The main thing is that the opimizer will / can do if bind variables different optimization techniques are used or not.
  There are two contradictory effects its regarding the binding settings.

  Effect 1: Reuse of cursor
  If the same is done again and again and again. Maybe different sessions. Then using binding settings is essential. Why? Because the same cursor can be reused, which saves a lot of time for analysis. This occurs mainly in OLTP systems. The idea behind this is that to do the same action, just for a different ID (ID in order for example) will result in an identical implementation plan.

  The result: Faster analysis time and less consumption of memory, because the same cursor can be resused between different sessions.

  Effect 2: Correct assumptions

  According to a filter expression, some using the value of the OBC will make an assumption based on statistical data the number of rows is returned because of this expression and the value.
  Speculation between a literal value and a bound value may be different. In many cases exist technical opimization (bind peeking etc.) to the same literal conjecture binded proposal.

  But there are exceptions, for example a condition such as the following will result in different estimates

  column between 10 and 20
  

  column between :P1 and :P2
  

  There are as well other effects.

  Result: The CBO can make assumptions better if literals. But most of the cases the proposal is identical.

  Conclusion: Literal values are useful if you do large queries where the output size depends strongly on the parameters provided, and where you run that very few of these (OLAP) queries.
  Binding settings are usfull when the same execution (OLTP) need a grand plan number of queries.

• CONSIDERATIONS OF MWA PERFORMANCE TEST

  Hi all
  
  We want to perform tests on our MSCA Fwk solutions especially manifest picking performance. Majority of orders shipped from our warehouse are orders of line 1.
  
  We must ensure that the system performs well enough for the company to continue operations post go-live.
  
  Can you please share your experiences on the data to be entered? How many orders to execute during the test to get a clear picture of performance.
  
  Are there specific aspects to be taken into account?
  
  Kind regards
  Arun.

  I think you need to do 2 types of performance tests:

  1. load tests
  Know what kind of charges you expect to see on the system.
  a. number of users
  (b) the number of transactions
  c. parallel transactions in EBS
  Set the system to reproduce that this charge and you should be able to pass with an average number of trnasactions running activity.

  2. stand-alone speed trials
  To do this you must make sure that the system is more fast/fast.
  Find a way to the device a technique to measure the amount of the difference.
  For example in our warehouse, we did a test based on the following points:
  1. check the time taken to enter data into the MSCA vs Legacy system is based on the number of iterations of scan/capture and not a quantity of function fo
  for example 96/6 pack are analysable. If you have a quantity of 1000 > it becomes a palette
  Given the conditions above a quantity of 96 would be a single iteration of data entry in picking manifest (items C.-a-d./quantite/lot)
  If we have a quantity of 15 it would be 3 iterations (6 + 6 + 3)
  2. find the distribution of the data in the warehouse.
  To make this excerpt, order lines all delivered over a given period
  Calculate the number of iterations you do. (handle in excel)
  Build your distribution boards
  Once you do this measure the time in Oracle vs system existing for each range
  Qty per range * delta time would give you more time by range
  Summation of all beaches gives you the total time.

  It is a very concise explanation. Please let me know if you need additional information

• WebServices API performance test. BB10

  I would like to test the performance of my Application that uses the BB WebServices API for BES10.

  How can I add false devices to perform the test?

  I have not found any BlackBerry tool or third-party applications.

  Thank you

  You cannot add a fake device.  You can create users in the system using the BWS with the API "createUsers.

  You can create administrative users who do not have a device, but order of queries users device information (device with users), they must be registered and then company activate their device against that account which was created (using the email address provided when they were created).

  A number of companies use BWS (BB WebServices) available to their users prior to their receiving device user.  Once they receive their device, the user will add an account using the Enterprise Activation password that was set for them when they were saved/created.

  In the absence of the user to activate their (physical device), you will only have the user objects stored in the database with no realization of activation (No PIN, the device type, model, OS version, etc.).  You can still use BWS for the users from the list, add it policies, add them to groups, etc.

  I hope that clarifies things, even if it is not the result you're looking for.

  In fact, you can take the exam now and eventually win the 11g PERFTUNE ECO credentials when you either:

  or

• Performance test to access compressed tables

  
  Hi all

  I'm reading and applying the queries in this article:

  http://www.Oracle.com/technetwork/issue-archive/2010/10-Jan/o10compression-082302.html

  I invite myself when you run this:

  Col value noprint new_value by start_cpu

  Select the value

  v $ sesstat s, v$ statname n

  where sid = (select sid from v$ mystat where rownum < 2)

  and s.statistic # n.statistic = #.

  and in n.name ("CPU used by this session")

  /

  Col value noprint new_value by start_reads

  Select the value

  v $ sesstat s, v$ statname n

  where sid = (select sid from v$ mystat where rownum < 2)

  and s.statistic # n.statistic = #.

  and n.name in ('logical session bed')

  /

  What values can I give to start_cpu and start_reads?

  Thank you.

  You can remove the line and do the math yourself. The new_value variable is specified to contain a column value and should just take the value ininital and keep it for the final statistical snapshot: http://docs.oracle.com/cd/E11882_01/server.112/e16604/ch_twelve013.htm#SQPUG034. If this does not work in your system, you can try to find the reason - or just calculate the difference between the value of the beginning and the end.

• VSAN Proactive Test - Multicast

  Not a biggie... just curious to see if other people running vSphere 6.0U2 / VSAN 6.2 see the same behavior.

  I have 2 clusters x VSAN, cluster mgmt to 1 x 4 nodes, cluster VDI to 1 x 6 knots. And now after the update when I run Multicast proactive tests (passing all btw). I find that in my results, 1 x node is missing in each result set...

  In the 4 cluster nodes I get only nodes reported for 1-3, and in the 6-node cluster, I get the nodes 1, 2, 3, 5, 6, results reported dethrone strange

  Everyone see the same kind of results?

• Satellite L70 - B - Radeon R9 M265X crashes after the test

  Hello

  Recently, I upgraded my Toshiba Satellite L70-B-130 windows 8.1 for windows 10.
  I got the same problem as many others with INTERNAL_POWER_ERROR but that has been resolved.

  (After starting for the first time I quickly disabled my AMD card and did the update of Windows).

  My driver for the AMD version is 15.200.1055.0 (WHQL / win 10/64)

  Now, everything is very stable.

  I tried 3DMark for some performance tests and after 2 minutes comparative analysis of my laptop stops suddenly due to overheating, I guess that.
  I had to leave the laptop have a cooldown, and then I could start over.

  When I was on windows 8.1 I don't have this problem, 3DMark worked well.

  It seems that the driver is the problem, maybe the coolingfan isn "t put away or something.

  Are there other people who have the same problem with the Radeon from AMD?

  If all goes well there will be a driver update shortly.

  Kind regards

  Jack

  Perhaps the latest AMD driver solve the problem?

  Hello my name is Luiza and I have a Dell Inspiron 3521.

  A couple of weeks ago, my laptop started showing blue screens. I tried to get it back in many ways, and none of them has solved my problem.

  Then, two days ago I was able to recover to factory settings, but the problem was still there (blue screen).

  When running a performance test, he gave the following error message:

  Error Code 2000 - 0151

• What happens when JOINT-2 performance is exceeded

  Hello

  We have JOINT-2 with about 20 pairs of vlan inline in the test environment. What happens to online traffic ourselves, said a flow of 500 Mbps? Falls of traffic or is it transmitted without IPS inspection.

  If you exceed the capacity of the sensor monitoring, then the packets that cannot be monitored will be abandoned by the sensor.

  NOTE: 500Mbps isn't a number of absolute performance for the sensor. It's a level of performance that the sensor has been testeed to be able to manage for certain types of traffic used in the performance test. We don't know exactly how much traffic the sensor will be able to manage to your network. The JOINT-2 will probably handle around 500 Mbps is a lot and even most customer networks. However, the networks vary, and in some networks, it can handle quite a bit less traffic and other networks can handle even more.

  So the question is not what will happen if you send more than 500 Mbps, but rather what will happen if you send more traffic than what the sensor is able to monitor. And the answer is that all traffic that cannot be monitored because of the limitations of performance will be dropped by the sensor.

  The only time where the packets are forwarded without inspection is if sensorApp has ceased to monitor all packets (a reconfiguration or an upgrade is in progress, or the process of sensorApp crashed) AND the functionality of the software workaround August kicks. Which case all packets will be forwarded without analysis.
