You have multiple CPUs, so a threaded process can theoretically reach
100*ncpus cpu usage.

I just built top-3.6 on such a system, though, and it does report a

thinking of Solaris's own prstat command?
Heh. I released 3.6 with new SunOS code

Ahh, thats makes sense,

One problem is that method doesn't scale to lots of CPUs. On a Sun
T2000 a non-threaded process consuming all of one CPU would only report
3.12 %CPU in that case (100/32).
I agree. The alternative is having a 10-thread process on such a system
report 1000% cpu utilization,

Actually it doesn't. IMO, %CPU should be biased for all available
cpu, not just a single cpu. In other words, a

Note that IRIX's top does not bias for availabile CPUs -- I've seen

What it comes down to is that depending on the nature of the
