Hello,
I have a RH5 machine where load is quiet inequally distributed, as
reported by sar:
CPU %user %nice %system %iowait %steal
%idle
Average: all 3.26 0.00 1.80 0.02 0.00
94.92

98.76
The machine runs apache (prefork-mpm) which serves php pages from an
NFS mount.
As the machine is not very loaded, it's not really a problem. But I'm
wondering what will happen when load rises.
Should I worry about weirdness ? Is it possible to alter the way the
scheduler work ?
Thanks !
Marc
