I have three machines. 1) stewart - running 7.0 (2.8gig p4 dual core) 2) bsd1 - running 7.0 (2.8gig Xeon Hyperthreaded) 3) bsd2 - running 6.2 (2.4gig Xeon Hyperthreaded) Now if I run tests that max out cpu (at least I think they do).. I see <1> or <2> drag down to 1% idle/ even 0 %idle. However <3> never drops below 50% idle.. it preforms a lot slower too.. which I expect since it is somewhat of an older processor.. but in running say top -S I see CPU 1 always running the idle process... Is this an accounting error that is being seen? aka top does not know how to display things .. or is this a scheduling error.. i.e.. move to 7.0 and life will be better :-D Thanks R -- Randall Stewart NSSTG - Cisco Systems Inc. 803-345-0369 803-317-4952 (cell)
