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
Make sure the battery isn't dead. Most RAID controllers drop to non-BBU speeds if they detect that the battery is faulty.
