what filesystem is being used. There is a thread on the linux-kernel mailing list right now showing that ext4 seems to top out at ~360MB/sec while XFS is able to go to 500MB/sec+

EXT3 on Centos 5.4

Plan to try and see if I have time with the new machines to try FreeBSD+ZFS. ZFS supposedly makes good use of memory and the new machines will have 72GB of RAM.
