hi all,
below is the output of top off a machine i have, sorted by CPU utilization.
my question is, how can all 8 CPUs say they're pegged at 100% user utilization, when there are just these 8 processes saying they're using 25% of a CPU each, and no other processes showing up taking any resources? i have run this test on other machines and they act as expected. i found this b/c this node was running a lot slower for some reason, and i can't figure out why. there are no error messages anywhere...
