Anybody else’s VS2010 is extremely slow when closing code editor tabs?
Opening a .cs file is instantaneous but closing a tab takes ~8 seconds. I have uninstalled Power Commands and the Productivity Power Tools, the only other installed extensions are ReSharper (disabling it did not help) and the Color Theme Editor. I do have the UI Automation Performance Fix installed.
I tried most suggestions from Visual Studio Optimizations question; made sure the settings are saved locally; disabled the outlining mode; disabled the Anti-Virus — nothing helps.
Googling only finds generic “VS2010 is a pig” complaints back from the Beta1 times. I even tried installing a few recent hot-fixes from https://connect.microsoft.com/VisualStudio/Downloads (KB2201993, KB2123002, KB2106584, KB981107, B2268081) but nothing seems to help.
Any ideas anybody?
–UPDATE—
Another clue: it only seems to happen for some solutions but not for others! Why would it be solution-specific?!!
Deleting .suo file helped!
Similar case was reported here but it involved a huge .suo file while mine was <1Mb
Another mention of similar problem can be found here in their case it was the debugger that was impacted.
Thanks to Sysinternals ProcessMonitor for the clue!
