How can mysql use 160%? Is this a reporting bug in top because mysql

You have multiple CPUs, so a threaded process can theoretically reach
100*ncpus cpu usage.
Ahh, thats makes sense, thanks.
Actually it doesn't. IMO, %CPU should be biased for all available cpu, not
just a single cpu. In other words, a single-threaded process running on a
two processor box should never see more than 50% cpu. That's how top
computes it for SunOS. But for freebsd top only displays whats in the proc
structure and I don't know off-hand how the kernel records it.
