I’ve been running VS2010 Professional for some time, and recently upgraded to Ultimate (installed on top of Professional).
Ever since, the memory usage seems a lot higher (~ 150MB in idle with no project loaded), the initial loading of the product is a lot slower, and general performance is slow.
Is there any way to finetune performance of Visual Studio? (For example, disable some functionality of it, etc)
Go to tools => options => And look through the addons that you may have installed. When i upgraded from Professional to Ultimate on the same machine i faced the same issue.
You can run visual studio with the following command line switch to load devenv without any extensions devenv.exe /resetaddin http://msdn.microsoft.com/en-us/library/xee0c8y7(v=VS.100).aspx
You could always look at the task manager to profile the resources being consumed. Or even better from the command line run devenv /log output.txt to log all activities performed by VS during the load, may be you would get some hints from there.
