What PowerEdge-model is it, dual or quad? If dual, did you try to
disable HTT in BIOS?
poweredge 1850 bi cpu xeon 2.8
what's the HTT????
It's hyper-threading, the cpu have some extra registers, so the cpu
can get some more work done (in theory) during one cpu-cycle. But most
of the time the improved performance is neglible. If HTT is enabled
one cpu will show up as two logical cpu's.
