Firebird 1.5 has a Classic Server version for Windows which should
work on a hyperthreading CPU.

But, this message was posted on Firebird-Devel, recently:

<<I have done some extensive bench mark testing over the last couple of weeks
with Firebird 1.5 rc6 and IB7 and IB6 and have found that IB runs vary fast
in all situations - inserts,updates,deletes,starting and commiting
transactions even when compared to IB6 on a hyperthreading machine firebird
still looses out, BUT with Release candidate 7 the picture changed
dramatically. Now Firebird is running extremely well and outperforms
Interbase6 and 7 by miles.>>

So, I guess the best way to be certain at 100%, would be to try it out
