All versions of FB (SuperServer-Windows) up to now will NOT take any
advantage from Hyperthread. Let the FB process to be attached to just
1 of the virtual CPUs.

Anyway, you can make some tests with Classic version of FB.

m> Hi

m> Does Firebird 1.5 (Superserver) support Hyperthreading? i've searched
m> google, but i found some that said it should work and others said it
m> wont...
m> (it runs on a P4 2.8C and Win 2003 Server)

m> should i disable Hyperthreading? is it recommended to set CP Affinity
m> to both (Virtual) CPUs or just one?

m> i've done some quick tests (but not with really high load) with HT on
m> and CPU affinity set to both CPUs and it seems to work.
