Ah, I am sorry. I searched the -current archives but I didn't find
anything related. And yes, I supposed that this problem was an
accounting issue, since the scheduling works fine indeed.

Thanks,

processes only consume system time ????

2000-09-21 Thread Jose M. Alcaide

This happens with freshly built -CURRENT, on an uniprocessor machine:

$ cat loop.c
main() { while (1); }
$ time ./loop
   [ wait for ten seconds... ]
^C
real0m9.982s
user0m0.000s
sys 0m5.689s

Uh? Other utilities, such as top(1) and systat(1) show that 100% of time
is accounted to the system. I imagine that this is related to SMPng...

Any clues?

Cheers,

Yes.  This is a FAQ.  The accounting is screwed up, and some of the
statistics are wrong.  Your system is scheduling processes close enough
