With procps-2.0.3-1 as included in Lorax 6.0.55, top's behavior has changed such that %CPU gives the share of CPU time of one processor since the last screen updated. From man top(1) %CPU The task's share of the CPU time since the last screen update, expressed as a percentage of total CPU time. I believe that this is caused by the change in determination of HZ in proc/sysinfo.c
This should be fixed in the Raw Hide procps-2.0.3-1. Please reopen this bug if not.
Whoops, this is still a problem in procps-2.0.3-1.
The bug is in the man page. People report this as a bug whichever way it works...
The man page describes the behavior exhibited by top in procps-2.0.4-2. As far as I'm concerned, this bug can be closed.
Thanks!
