    What does gstat look like on the server when you are doing this?

    Also - does a dd locally on the server give the same results? You should get
    about double that I would estimate locally direct to disk. What about a dd over
    NFS?

    What is the server spending its time doing? (top?)

    If you are looking for the best performance, you might try a RAID 0+1 (or 10
    possibly) instead of RAID 5.
