Hi Colin,

this is much closer to (and nicer than) what I had in mind. But it seems time-based. Does it include tools to relate to PC?

Hi All,
I'm badly in need of a histogram-based profiler for the VM I'm working
on. This is something that produces a histogram of time taken against PC,
insead of time taken against function.

Another option would be DTrace/Instruments, if you're running Leopard.
