>Synopsis: top cpu usage is wrong before first refresh
>Category: system
>Environment:
System : OpenBSD 5.9
Details : OpenBSD 5.9 (GENERIC.MP) #1888: Fri Feb 26 01:20:19 MST
2016
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
top command reports wrong CPU usage before being refreshed after the
delay.
This is problematic in batch mode because the output is always wrong
>How-To-Repeat:
top -1b always display the same cpu usage
using top in interactive mode also always display wrong cpu usage
before being refreshed (same cpu usage as batch mode)
>Fix:
I don't have a fix
