My VS2010 solution is a large scale one, with 100+ source/header files, and several external library being included. I use VAssistX plugin. Yesterday I added a new .cc file and it started getting slow when editing. Very lag when typing.

I tried to rebuild VS2010 intellisense database (Project > Rescan Solution), and rebuild VAssistX symbol database. Is there any other thing I can try in order to fix this issue? Or any way I can find out what's the root cause.

PS: I am guessing this lag is due to symbol parsing. Whenever I type in that new file, VS2010/VAssistX is looking up or updating the symbol database. Somehow this operation is cause lagging.

    Visual Assist turns off the VS intellisense parser so you'll need to focus on VA for this problem. This is a memory-hungry kind of add-in so make sure your machine has enough oompf to support it. Never try using it if you have only 2 gigabyte of RAM for example. Contact the vendor for support. – Hans Passant Aug 08 '13 at 10:22
  • I got 8GB ram and usually keep 1-2GB free memory available. I am worried about the include file in the new .cc file may cause a loop, which causing VA repeatedly parsing some files again and again. Is it possible and how to find out this issue? I am trying to use "Process Monitor" to track if any unusual file accessing by VS2010. – Stan Aug 09 '13 at 08:21
  • I noticed that the CPU (the core) is always at 100% when editing. – Stan Aug 09 '13 at 10:07

I know it's an old question but for those that still work with it, Visual Studio 2010 doesn't cope well with a lot of files being open. This might be the problem here. Try right clicking your current file and selecting Close All But This and see if that works for you.
