Nope, no performance problems on the clients from what I see. They're builds just crank along. They *seem* to be doing a bunch of parallel builds. If you're familiar with ClearCase, it lets you specify a bunch of hosts to do parallel builds on, so you can farm out a build job across multiple hosts.
I think once I can figure out which file(s) they're doing the getattr() calls against, I can then chase down the problematic change in their build setup or whatever.
