One thing I noticed on a dual Xeon running Fedora Core 2 compared to a dual Xeon running RH 3WS is the difference in the output of "top". Under the Linux 2.4 kernel of RH 3WS I see the individual cpu states shown as ... CPU states: cpu user nice system irq softirq iowait idle total 0.0% 0.0% 0.0% 0.0% 0.0% 0.0% 99.9% cpu00 0.0% 0.0% 0.0% 0.0% 0.0% 0.0% 100.0% cpu01 0.0% 0.0% 0.0% 0.0% 0.0% 0.0% 100.0% cpu02 0.0% 0.0% 0.2% 0.2% 0.0% 0.0% 99.6% cpu03 0.0% 0.0% 0.0% 0.0% 0.0% 0.0% 100.0% whereas under FC2's Linux 2.6 I only see... Cpu(s): 0.2% us, 0.4% sy, 4.1% ni, 95.3% id, 0.0% wa, 0.0% hi, 0.0% si Just curious why the output has changed from "top". Jack
