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.
