Hello,
I've noticed that top now is now unreliable in measuring system
performance.
[timon at timon timon]$ uname -mv
FreeBSD 5.2-CURRENT #19: Sat Mar 13 16:27:48 MSK 2004
root at timon.nist:/usr/obj/usr/src/sys/TIMON i386
options SCHED_ULE
(cvsupped just before rebuilding kernel & world)
top gives weird CPU/WCPU usage: only first (rarely, first couple) of
processes displayed have non-zero CPU/WCPU usage, all others have zero
cpu usage, but totals, shown in second line of top output differs from
sum of values in CPU column alot. Same with ps.
E.g.:
51 processes: 2 running, 49 sleeping
CPU: 20.2% user, 0.0% nice, 3.5% system, 2.3% interrupt, 74.0% idle
Mem: 168M Active, 141M Inact, 98M Wired, 716K Cache, 60M Buf, 91M Free
Swap: 231M Total, 231M Free
