Thanks a lot for all the comments.  The fact that both my windows box and the old linux box both show a massive performance improvement over the new linux box seems to point to hardware to me.  I am not sure how to test the fsync issue, but i don't see how that could be it.

The raid card the server has in it is:
3Ware 4 Port 9650SE-4LPML RAID Card

Looking it up, it seems to indicate that it has BBU

The only other difference between the boxes is the postgresql version.  The new one has 8.4-2 from the yum install instructions on the site:

Any more thoughts?

Sure, but the original post was because the brand new server class
machine was performing much worse than the single-drive desktop
machine *on the same queries*, which seems like an issue worthy of
investigation independently of what you suggest.
