i think Intel's P4 HT (hyperthread) do more harm than good. i'm thinking about asking LT to turn off the HT on my server. my Intel Celeron server at theplanet performce better than P4. did any of you notice any difference that HT make?
you're right. HT does help. i can barely remote desktop in with HT turn off. the only reason that i suspect HT wasn't helpful is because it is not physical cpu but logical. it's not like dual core or dual cpu but yeah, i believe it is the software configuration that is causing the problem and not HT.
