Slow vSphere client

After upgrading VMware Virtual Center to 4.1, I noticed the vSphere Client took almost a minute to connect after authenticating.

Delete personal settings for client (clears saved server list and downloaded certificates) :

• HKCU\Software\VMware\Virtual Infrastructure Client
• HKCU\Software\VMware\VMware Infrastructure Client

Windows 7 users can also disable desktop composition to improve preformance:

1. Right-click the shortcut for the vSphere Client and click Properties.
2. Click the Compatibility tab.
3. Select Disable desktop composition.
4. Note: This disables Aero desktop effects while the application is open
5. Click OK.
6. Run the vSphere Client.

Deleting the registry keys reduced my load time to almost a quarter of what was prior.
