One problem is that method doesn't scale to lots of CPUs. On a Sun

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, and/or having the sum of the cpu utilization
column be 3200. Not sure which is worse.
I just built top-3.6 on such a system, though, and it does report a
simple "main(){for(;;);}" process as consuming 100 %CPU. Maybe you're
thinking of Solaris's own prstat command?
Heh. I released 3.6 with new SunOS code that didn't adjust for number of
cpus, and someone flagged the behavior as a bug. So you're right: 3.6
doesn't do it this way. But 3.5 did, and it seems at least some people
prefer it that way.
