I have lots of code paths taking lots of different classes of locks. My problem is I don't know what to ask perf for to see if I have a mutex that is heavily contended, and so some threads are spending a lot of time asleep waiting to acquire it. As I said, this is probably pretty basic stuff, but I'm not usually much of a userspace guy...
