When working in Visual Studio 2008 with a large C++ solution of 179 projects,
the whole environment is very slow. Simple things such as selecting text in
the editor (without modifying anything), resizing Visual Studio, right
clicking projects to bring up contextmenus and so on, all causes the
environment to hang for 5-10 seconds.

I still have Visual Studio 2005 installed.
I have Visual Studio 2008 installed.
I have tried installing the VS2008 hotfix.
I have tried deleting the .ncb file.

The C++ solution that performs poorly with VS2008 consists of 179 projects,
mainly MFC and ATL. The same solution worked OK with VS2005 (before upgrading
the solution and project files).

I also upgraded a C# solution with 33 projects to VS2008, that worked fine
(except for some compiler/linker errors that I fixed).

I'm using a multiprocessor pc (4 cores), I have tried installing VS2008 on a
single core pc, and there it seems to work much better.

Please help.

Best regards,
Thomas Pagh

Experiencing very similar problem, except VS2008 is slow on just one specific
project, not entire solution.
Whenever I do something with the code, it just hangs for 5 - 30 seconds.
VS2003 and VS2005 never had this problem.

I think it's intellisense trying to go through all the includes (tons of
them, when compared to other projects).

Nevertheless, the VS2003 & 2005 intellisense didn't work at some places in
that project, which seems to be fixed VS2008, but I'm starting to think that
this fix is the real problem here.

If we hide the TeamFoundationServer-Toolbar under VS2008, that seems to take
care of the problem, we are using TFS2005.
Is there any fixes on its way to this problem?

There is a hotfix available that addresses at least some of the intellisense
performance problems in VS 2005.

http://support.microsoft.com/default.aspx/kb/943969/en-us

There is also an interesting blog post from the author of the hotfix explaining
the issues in detail, but I can't find it. Maybe someone else can respond to
this NG with a link to that.
