I have been using it some... BUT only for some testing. Didn't see a HUGE improvement from it on 2k, But haven't tried it yet on my 2003 boxes. On the other hand I wont put it in production on 2k simply because I have a LARGE customer with several MS reps on site, and they were running around disabling the hyper threading on all the 2k servers....... The funny thing is several models of HP and Dell are coming out of the box with it enabled. So if you open up task mgr on a Dual and see 4 procs you know what happened.

We have server based on Intel 7501 Dual Xeon chipset and the manufacturer turned on HyperThreading support in motherboard's BIOS though it isn't recommended using HyperThreading with Windows2000 on Intel's site! Does anyone have real expirience of using this technology on terminal servers and whether the real gain of productivity in the multiuser system turns out from it???
