Visual Studio freezes when I save then switch file

Environment : Visual Studio 2010 v10.0.31118.1 SP1, Addins : jetBrain,DXCore,VisualSVN Windows 7 (up to date)

Since a long time Visual Studio is really slow, so I tried to see how to reproduce the problem and it's really simple : I add a letter to a file, save and then try to open an other file.

Then Visual Studio freezes for 10sec or more. if I just save or open a file there is no hang at all.

I looked at the processes with ProcEx.exe and I saw that devenv.exe has a lot of I/O.

So with ProcMon I tried to see what was going on, and I saw that visual studio opened every single file of my web site, and every file of the temporary asp.net files folder linked to my website.

So I looked at the stacktrace of every "ReadFile" operation and I get

So do you have any guess ?

Thanks


I found the solution : run CCleaner ! it seems that Visual Studio uses a lot the temp folder, and avast antivirus is scanning it every time you open/save a file.

So I couldn't had a filter in avast for the temp folder, so I preferred emptying it.


Please consider downloading the Visual Studio 2010 Diagnostic Tool and sending the results to Microsoft. The tool will collect a variety of performance information that will help the Visual Studio team come up with a solution (if it's an issue with the core product).
