Super long Visual Studio pauses connected to TFS

Ever since I connected to TFS, Visual Studio has started pausing for very long periods of time (30-60 开发者_运维百科seconds), even when doing things that probably shouldn't be hitting the server. It eventually comes back, but it's very disruptive. The server is not local, but I'm told that it's not really doing much, nor does it have a lot of traffic.

Has anyone experienced this, and does anyone know what I might do to diagnose the problem?

Using Fiddler, I saw that each operation that caused a pause involved downloading a 3MB repository.asmx file. The server doesn't have a great upload speed, so that was causing the delay. I had a bunch of stuff checked out, and as I checked it in, that file got smaller and smaller. Now it's down to about 4KB, and the delay is only a couple of seconds.

Thanks for the help!
