Not being one to hijack threads, but I haven't heard of this performance hit
when using HT, I have what should all rights be a pretty fast server, dual
2.4 Xeons with HT 205gb raid 5 array, 1 gig of memory. And it is only 50% as
fast as my old server which was a dual AMD MP 1400's with a 45gb raid 5
array and 1gb of ram. I have read everything I could find on Pg performance
tweaked all the variables that were suggested and nothing. Which is why I
subscribed to this list, just been lurking so far but this caught my eye.

Some people have reported that things actually slow down with HT
enabled. Have you tried turning it off?
