We've received feedback, both directly from developers and in the forums, regarding slow performance of the Visual Basic 2005 IDE in certain situations (larger projects, projects with many errors, etc.).
I’m sorry that these issues made it to production and degraded the performance of the IDE. The Visual Basic Performance team is working hard to address these issues via hotfixes and the upcoming Visual Basic 2005 SP1 while we work on engineering changes to make sure that issues such as these never make it into a shipping product in the future.
Based on this feedback and forum posts, we've been working with customers to address these performance issues. We recently released a performance hotfix to address the following areas of Visual Basic 2005 performance:
1. Improves the performance of single-stepping (F10) debugging.
2. Improves the performance of Task/Error List Refresh.
3. Improves the performance of Intellisense.
You can learn more about this hotfix in the KB 920805 article (http://support.microsoft.com/kb/920805/en-us). In order to get this hotfix, you need to contact support and reference KB 920805. Details on contacting support can be found at http://support.microsoft.com/contactus/ ws=support.
Note that this hotfix rolls up all peformance hotfixes to date, so installing this hotfix will give you the best IDE performance.
Again, we appreciate your feedback and we thank you for your patience while we address these issues. Please contact vbperf@microsoft.com if you continue to see issues after applying this hotfix.
Thanks,

Foolios
RH,
Thanks for letting us know you're having problems. Can you contact my team at vbperf@microsoft.com and describe to us your project and where exactly you are seeing performance issues with Visual Basic 2005 when renaming controls.
We'd love to work with you to address the issues.
Thanks,

Do I have to call to US
It's very expensive to make call from Indonesia to US. Don't you have other option, email may be
thanks

The fix is Visual Basic 2005 only. If you are seeing performance issues in C#, please follow up with the C# team on their forums.
Thanks,

Hi Vasil,
Unfortunately i haven't found any back door link yet. i'm also desperate to get it since Ms Indonesia didn't pick up my call couple days ago. i don't understand why Ms makes it hard to obtain the hotfix.

Nice try..
But still a Loooong way to go before it even gets close to vs 2003.
Our standing VB.net performance problems after this hack..
a) Still crashes within background checking
b) Still takes almost twice as long to compile the same code as vs 2003
c) Still takes over the OS ( scren lockups) and goes to sleep..
d) Still does not like multithreading ( multiple CPU's)..
e) Still does not work ( means takes too long) with VSS
The good..
a) 150% betetr than previous which was unuable, adn could not be called a compiler..
b) Crashes done to about 2 to 3 a day, much better than every 1/2 hour..
c) Stupid report to MSoft scren now works properly, then crashes..
Bottom vs 2005 VB.NET is still not a commercially usable product, and this si just performce let alone the long list of brakign issues with vs 2005 and VB.net generally..
VERY SAD!!!

I installed VS2005 SP1 and it did nothing for the slow response time in the VB.net IDE. Specifically when renaming controls....
Terrible...

I'm desperately looking for that hot fix. I you have any “back door” link or any idea where I can find it (beside calling to MS) please tell me.

Vasil
