VS2010 loads slowly. Can I profile extensions' respective startup time?

Question

I have a simple question. Is it possible to somehow get a log of what is taking so much time to load when starting VS2010? On a default install, starting the IDE is very qui

No need to upvote this answer, give it to Antony instead (or edit it into his, I don't have enough points):

1. Run devenv /log,
2. Close the IDE to close the log / stop logging,
3. [Win]+[R], run "%APPDATA%\Microsoft\VisualStudio\10.0\ActivityLog.xsl"
4. Wait for it to load in Visual Studio,
5. Press [CTRL]+[ALT]+[F5], select ActivityLog.xml, or paste "%APPDATA%\Microsoft\VisualStudio\10.0\ActivityLog.xml" into the browser.
6. View the formatted html.

FYI: Here was one of my slow extensions that I will get rid of and file a bug report in:

Answer 2

You can use devenv /log as detailed here: MSDN Blogs: Troubleshooting Extensions with the Activity Log.

1. Run devenv /log
2. Close the IDE again to close the log Win+R,
3. Run %APPDATA%\Microsoft\VisualStudio\10.0\ActivityLog.xsl
4. Wait for it to load in Visual Studio
5. Open %APPDATA%\Microsoft\VisualStudio\10.0\ActivityLog.xml in a web browser and it will format itself nicely.
