Re: performance on new linux box

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:
http://yum.pgrpms.org/reporpms/repoview/pgdg-centos.html

Any more thoughts?
