Speed up vSphere client on Windows 7

KB article 1027836 explains that the vSphere client may seem slow when running on Windows 7 systems, and that this is especially noticeable when maximixing the window, which forces a redraw of all the panes inside the client.

To improve vSphere client performance under Windows 7, you can disable a feature called desktop composition as follows:

  1. Right-click the shortcut for the vSphere Client and click Properties.
  2. Click the Compatibility tab.
  3. Select Disable desktop composition.
  4. Click OK.
  5. Run the vSphere Client.

    Thanks for the tip, I’ll give it a try.

    People need to complain about this to vmware. This needs to be fixed, how long has windows 7 been out and their app is not fully compatible? Horrible! I would expect this from a small company.

      Hi Dave. Thanks for responding.

      Just to be clear its technically not a compatibility issue as the vSphere client is fully supported on Windows 7.

      The issue is with the “Aero” features of the Windows 7 UI. Some may find Aero to be “pretty”, but it also requires more CPU and graphics overhead. How noticeable this CPU tax is depends on both the system and the application.

      So what you’re basically doing here is disabling Aero to reduce CPU and graphics overhead to speed up the application and this is commonly done for many 2D apps that don’t benefit from Aero and certainly not just vCenter.

      There’s rumors abound that future versions of the vSphere client may be based on Adobe Flex so that platform may also offer some improvement.

        No, this is the vSphere client, not anything to do with memory or CPU. I’m on a Quad CPU machine with 12GB of ram, and it is the slowest app on my system to refresh the screen. Disabling Aero helps, but still very slow. I have 8GB+ ram free and 4 3.2GHz cpu’s mostly idle when running the client.

    This workaround ends up entirely disabling the Aero theme whenever the vSphere client is launched, so ALL apps and desktop get switched to Basic. Annoying! This is the only app I’ve used on Win7 so far that has this issue. Vmware should get their act together.

  4. Mike P. says:

    I have to agree with Ted here. It’s rather annoying that when vShpere’s running with this workaround Aero is disabled all together. Vmware should get this straightened out or at least say why they can’t.

    I’ll guess I’ll add this to the couple of apps that I have to run in a 32bit XP VM.

    Totally not acceptable. Only application I have ever used to be this slow at rendering graphics. Come on vmware, we don’t pay you the big bucks for this…
