As stated in my post directly above yours:

I was running a stress test on US West to see what kind of speed it could handle.  It turns out it can easily handle the entire pool worth of speed right now, the issue was it was tossing out stales (no idles though).

I've found out why it was tossing stales, and will attempt another test tonight.  The goal is to consolidate the servers to a load balanced location to reduce the overhead of sync'ing servers all over the world, and to give us one location behind a provider that understands DDoS and will help us with perimeter level filtering if we are attacked again.  Cutting out some of the monthly costs is another plus.
