All,

I started playing around with the February 2008 version of GAX/GAT and have recently been dogged by VERY slow response when developing a guidance package. My guidance package started with the sample solution you get when you create a Guidance Package solution.

From experience (and warnings) I expected the Register and Unregister to be slow but even file saves are slow - a few minutes! The UI is unavailable during the save.

I do not have any problems with other non-GAT projects in VS 2005 (Team Edition for Developers).

I did some checking and found some great tips on how to debug slow performance in Visual Studio 2005. As a result of my research I downloaded and installed ProcessMon (procmon.exe)to monitor file operations originating from the devenv.exe process of my VS 2005 session. I found that during a save of any file, devenv writes to a file namedC:\Documents and Settings\xxxx\Local Settings\Application Data\Microsoft\VisualStudio\8.0\1033\ExpansionsXML.xml over 32,000 WriteFile operations. I'm not joking. I don't know all of what the data means but it sure isn't normal. I excluded the above file from my Virus Scan but there was no noticable improvement.

Does anyone have any similar performance problems with this version of the GAT? Why is this file (seems to be related to snippets) being updated and why so much? Any other tips to resolving this?

Thanks!
Daryl
