Cube Performance for the Refresh problem

• Performance using the virtualization problem

  If we compare our software installed in a physical host and a comparable VM (same CPU, memory), we notice that the product is twice slower when running in a virtual machine (guest operating system is Windows 2003, the use of an ESXi 4.0 host. The software uses a single CPU)

  As we are not in the production environment, we tried with all other VM turned off. We tested our VM with and without reserve of CPU (best results with), with and without memory (absolutely no difference) and 1, 2 and 4 vCPU

  After several tests, it seems that the problem comes from the use of semaphores: when replacing them with critical sections (but we cannot just replace), the performances are quite the same between the physical host and the virtual machine. All the code is executed with similar performance, but when using semaphores, the VM uses longer than the physical host CPU.

  Someone at - it something on such a problem ears already? Is there a reason to explain the poor performance when using semaphores Windows hosted by ESXi 4.0?

  For example, we wrote a simple program to compare hosted by ESX Windows semaphores (in our laboratory, it took 10 sec on a physical host and 22sec in a virtual machine):

  #include "stdafx.h".

  int _tmain (int argc, _TCHAR * argv)

  {

  unsigned __int64 nCount;

  NTickCount = DWORD: GetTickCount();

  HANDLE hSemaphoreBridgets = CreateSemaphore (NULL, 1, 1, NULL);

  for (nCount = 0; nCount < 10000000; ++ nCount)

  {

  WaitForSingleObject (hSemaphoreBridgets, INFINITE);

  ReleaseSemaphore (hSemaphoreBridgets, 1, NULL);

  }

  printf ("%d s\r\n duration", (: GetTickCount() - nTickCount) / 1000);

  CloseHandle (hSemaphoreBridgets);

  return 0;

  }

  I have your reference of profiling and found that he spends most of his time in these three Windows HAL functions:

  HAL 39.83%! KfLowerIrql

  HAL 19,82%! KeRaiseIrqlToDpcLevel

  19.07% hal! KeRaiseIrqlToSynchLevel

  Hot spots in each function are the access TPR (0FFFE0080h is the address of the TPR in the local APIC):

  HAL! KfLowerIrql:

  807168e4 890d8000feff mov dword ptr ds:------[0FFFE0080h], ecx

  807168ea a18000feff mov eax, dword ptr ds:-[FFFE0080h]

  HAL! KeRaiseIrqlToDpcLevel:

  807168a 0 8b158000feff mov edx, dword ptr ds:-[0FFFE0080h]

  807168a 6 c7058000feff41000000 mov dword ptr ds:------[0FFFE0080h], 41 h

  HAL! KeRaiseIrqlToSynchLevel:

  807168bc 8b158000feff mov edx, dword ptr ds:-[0FFFE0080h]

  807168c 2 c7058000feff41000000 mov dword ptr ds:------[0FFFE0080h], 41 h

  Since the local APIC is virtualized, TPR access usually causes a VM exit under hardware virtualization.  However, Intel has introduced FlexPriority, which prevents the release of the virtual computer for all TPR readings and some TPR Scriptures.  For this reason, ESX 4.0 by default x - VT for 32-bit Windows 2003 on Intel FlexPriority chips.  Unfortunately, FlexPriority isn't a panacea.  On native hardware, TPR access are usually only a few cycles.  With FlexPriority, TPR access which do not cause a VM output may still take hundreds of cycles.  Access TPR cause VM-output take several cycles of a thousand.  Fortunately, we still have the possibility to use binary translation.  Under the binary translation, TPR access usually take dozens of cycles.

  For this particular workload, you must configure your client to use binary translation.  On my system of Penryn, benchmark runs in 22 seconds using VT - x (with FlexPriority), but it takes 13 seconds using the binary translation.  (For completeness, it takes 90 seconds using VT - x without FlexPriority).

  Your client's situation is different.  AMD has never introduced an equivalent to FlexPriority technology.  However, if your customer has configured their VM to use the material support of the MMU, then the virtual computer will use AMD - V, which suffers from the same problems that VT - x without FlexPriority.  Make sure they have configured computer virtual for the MMU software support so that it runs using the binary translation. (For this guest under ESX 3.5 default execution mode is binary translation).

• Qosmio F50 - warranty for the battery problem

  I bought a F-50 from Toshiba to Saudi Arabia. He has a 3-year international warranty.
  But last month my battery or my adapter (No. Clue which one it is) started acting weird. I mean my battery charges to 60-65%.
  So I removed my battery and started using only the adapter directly and my laptop works very well.

  Recently, I called the service center and told them my problem and they confirmed that my battery is the real problem... OK fine...
  I also told them my laptop has 3 years international warranty and they provide a free service... they said that my laptop has 3 year warranty, but the battery has only 1 year warranty... which means I have to buy a new battery...

  I'm basically located in Chennai, India and I want to know if it's true. Is it true that the battery has only 1 year warranty?
  Is it possible I could get a battery without paying. Is there any body else facing this same problem? *

  And can someone tell me where I could give my phone to maintain it here in Chennai...

  Thank you (I hope you understand what I mean)... ;-)

  Yes it's true. Warranty covers the battery always one long year.
  It s any manufacturer will ask you; all batteries are covered under warranty for one year.

• BlackBerry plugin 1.1 for the eclipse problem

  I used my Eclipse SDK - 3.5.2 - win32 + BB plugin 1.1 Setup for more than a month without probs either.

  After a minor JRE 1.6 Online updated today, the workspace of Blackberry has simply disappeared without a trace.

  No entry on the menu bar and no BlackBerry option in preferences. Nada.

• graphic display of performance for the week or the last month?

  Using a VSphere Client 4.1.0 to display an ESX 4.1.0 Server, I am looking at the graph of the performance of the processor (for example).

  When I go into "Options", what I see under CPU options is 'real time' and 'last day '.  Below, time go specifications ('last n periods' and ' a + for ' are all gray.)

  Is there any where that I can set collection or the length to collect & graph interval a longer history, such as week or the last month?

• How can I get the best performance for the games?

  I have a Satellite A30 151 and he has an ATI mobility radeon 9000 igp 128 MB. I had a few problems in the game. I couldn't t get sufficient performance when executing some basic games. Are there updates or updates to driver for my ATI radeon display driver to increase his "performance?
  Answer [email protected].
  Thank you...

  Hi Ercan

  In my opinion, this is a common problem with laptops because performance laptops are not as on desktop computers, and there is no longer any possibility for updates as on desktop computers.

  Try to set all the graphics settings at a lower level. Maybe the performance will be better. I do it with the games I play.

• Wait for the rotation - problem with vertical centering

  What is the event to listen to determine the screen shot? I swore I saw someone talking before but search brings nothing relevant.

  I use x are coordinates for my layout and I have my coord y the value 10, which is excellent in landscape mode. When I turn to portrait, everything is centered vertically, which isn't what I want. I guess I need to listen to the rotation and change my details, but even when I start mode portrait and deply then the app, everything is still smack in the middle (vertically speaking) of the Simulator. I can't understand why this is.

  Hey miss breeder,.

  I was not completely successful with my orientation, but this is what I tried and got some sort of results. the only thing that is a problem, is that the fonts are appearing (possible incorporation question). but the listener is in the code and so here's the function:

  package
  {
      import flash.display.Sprite;
      import flash.display.StageAlign;
      import flash.display.StageOrientation;
      import flash.display.StageScaleMode;
      import flash.events.StageOrientationEvent;
  
      [SWF(width="1024", height="600", backgroundColor="#999999", frameRate="30")]
      public class SampleTest extends Sprite
      {
          public function SampleTest()
          {
              super();
  
              // support autoOrients
              stage.align = StageAlign.TOP_LEFT;
              stage.scaleMode = StageScaleMode.NO_SCALE;
  
              stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGE, onOrientationChange);
  
          }
  
          protected function onOrientationChange(e:StageOrientationEvent):void
          {
  
              if (e.afterOrientation == StageOrientation.ROTATED_LEFT)
              {
  
                  this.rotation = -90;
  
                  this.x = 0;
                  this.y = 1024;
  
              }
              else if (e.afterOrientation == StageOrientation.DEFAULT)
              {
                  this.rotation = 0;

  Hello

  
  

  Do you have a do deal with all nicely performace concern (that is to say CPU, memory, network or disk) with offset in VMtools version and the version of the material on any version of Esxi host.

  Yes, it could be the performance impact, but not specifically because of a link between VMware Tools v9 and HW version v8.

  VMware Tools 9 implies that you are on vSphere 5.1 or higher.

  And here the HW version 9 or higher.

  The HW version could have the impact on performance if you follow is not the version of vSphere.

  Notice that handling change when you go to HW v9 or higher (Web client)

• Conversion of sampling panelator for the version problem

  I can't get panelator to run on a non - dev machine.  I get the «...» Panelator.AEX' could not be loaded (14001) (48::46) error.  In the other samples fix by changing the regular, MDd MD debugging runtime library and compiling change _DEBUG for NDEBUG preprocessor.  In the example of projdumper, I also had to add a "_DEBUG #undef" line in the header file.  I use Visual c ++ 2008 Express to compile the examples.  Is it possible to compile the example of panelator for a release?

  I see a few problems.

  1. you use vs2008.

  the sdk is intended for vs2005.

  the main difference is that 2008 uses MSVCR90. DLL instead of MSVCR80. DLL

  that could be a problem.

  before you proceed to 2005, try to replace /MD /MT.

  which would cause the plugin to include all possible libraries in his code and it would be independent.

  plugin you throw the dependency walker tool.

  If you use / MT, should not be dependent on everything except of KERNEL32. DLL and that should fix this problem.

  2. some code of support can have contrary parameters.

  Check the properties of the files in the folder 'support code' in the panelator example.

  you might find some files that still have debug symbols or are defined as MD or MDd

  in general, windows XP service pack 2 comes with MSVCR and MSCRT version 7.

  If you are the plug-in is dependent on a more recent version that you place these DLLs on the host computer.

  VS2005 comes with version 8 of these DLLs and 2009 with version 9.

  the tool put dependency walker on the non developer machine and you will see that your plug-in is missing.

  I, personally use/MT and as far as the plugin regardless.
