How to turn on compression for TFS 2010 web services
In the past, we’ve turned on compression for the SOAP responses for the TFS web services. In TFS 2010, you must do it manually. In the future, I hope we have it turned on by default. It’s particularly good for teams that aren’t at the same location as the TFS server. For users on a high-speed corporate network, it’s not likely to matter.
