Sync points in Team System Load Tests
Sync points are something you can use to drive heavy load on a system. In some other tools, they're called "Rendezvous points". For example, you could have every user adding items to shopping carts at their own pace, then synchronizing so that they all check out in the same instant.
One of the nice aspects of Team System is its extensibility. Bill Barnett wrote a sample implementation for both web tests and unit tests using a SyncPoint class, a load test plugin, and blogged about it here: http://blogs.msdn.com/billbar/articles/528649.aspx.
