Description Jeremy Katz 1999-09-12 18:59:10 UTC
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
Comment 1 Jeff Johnson 1999-09-12 22:42:59 UTC
This should be fixed in the Raw Hide procps-2.0.3-1. Please reopen this bug if not.
Comment 2 Jeff Johnson 1999-09-12 22:44:59 UTC
Whoops, this is still a problem in procps-2.0.3-1.
Comment 3 Michael K. Johnson 1999-09-20 00:44:59 UTC
The bug is in the man page. People report this as a bug whichever way it works...
Comment 4 Jeremy Katz 1999-10-03 02:20:59 UTC
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.
