Hi Valadimir,
Thanks for your post.
One of the biggest culprits for Visual Studio 2005 slowness is Intellisense. What I frequently experience is that Intellisense is working nearly non-stop to "re-index"
symbols (or whatever you call it). There are some workarounds might help you:
Could you please check out this link to get a better understanding of Intellisense:
Intellisense Info
Then please check out this link for some macros that I've had a lot of success with:
Intellisense Macros
With those macros, you can turn off intellisense (without renaming any DLLs), restart it, delete the ncb file (which you can do manually, but this is a convenience)
and it can give you the status of Intellisense.
Hope this can help.
Best Regards,
Ziwei Chen
