Random-pausing will tell you what is your percentage split between CPU and I/O time.

Basically, if you grab 10 random stackshots, and if 80% (for example) of the time is in I/O, then on 8+/-1.3 samples the stack will reach into the system routine that reads or writes a buffer. If you want higher precision, take more samples.
