I have a hard time imagining that you'd get useful information from cross-posting this to the FreeBSD and CentOS lists. Their implementations of filesystems are completely different. If you use a CentOS NFS server, I'd recommend ext4. In benchmarks, I often see XFS perform better than ext4 in specific tests. JFS rarely does well. However, the last time I used XFS was for a system running Zoneminder. Benchmarks let us to believe that XFS would be a better filesystem, but in our actual implementation it couldn't keep up. The application couldn't delete data quickly enough when the volume was nearly full, so the volume would fill up and the system would fail. We only got it working reliably after switching to ext4.
