Windows Vista SP2 (Intel Core 2 Quad CPU) 2.40 ghz 4 GB RAM - 32 bit
Windows 7 SP1 x64 (Intel Core 2 Quad CPU) 2.50 ghz 8 GB RAM - 64 bit
Our EPR has many vb dll project (50).
All our projects are located on a local network path on a Windows 2003 server.
For loading a simple project with 3/4 forms and 2 classes about 30 seconds !!!: it is very slow compared to VS2008 (5/6 seconds) in all environment .
In all machines we have installed VS 2008 SP1 Pro and VS 2010 SP1 Pro all os are windows updated.
We have tried all suggested solutions found on internet:
* Install Windows Automation API 3.0
* Clear Most-Recently-Used List
* Disable add-ins and extensions
* Disable hardware graphics acceleration
But .... nothing changes VS2010 is very slow on start-up.
We are considering to revert to VS2008 is impossible for us to work with it !!!
Can you please help us ?
Best Regards

This is a major subject with Microsoft, as there are a lot of people identifying issues with the 2010 IDE (based on WPF).   You can only imagine how I feel (I have to use it on Windows XP at work).  Hopefully with the next version of the IDE, we will see the performance that we all need.

That article is talking about 2003 IDE problem, and at first I thought it would have been solved by now, and yet:

What I found is that the slowdown was related to addins/extensions and the MRU list (as described in this blog entry).  Once I’d cleaned out the MRU list and disabled the offenders it now starts in 8 seconds.

Visual Studio 2010 is a pig

Update: I installed the Express version of VS 2010 on another computer and have been using it regularly. It is much faster, and pleasant to use. Maybe there’s something about the Ultimate edition (TFS integration?) that slows it down.

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

Also, you should be able to contact Microsoft by sending mail to  This is a great research project for me:
Is it slow when loading from the network or even when loading from local drive?
