    slow data transfers w/ smb, scp

    Hi everyone,

    I am having a problem with slow data transfers with both Samba and scp. I have gigabit NIC's on both all three machines that I am transferring to and from, connected to a gigabit switch. My data transfers under both smb and scp average around 21 MBit/s, (I am using nload to monitor transfer speeds).

    The machines are configured as follows,

    1) desktop

    AMD Athlon 64 X2 6000+
    6 gig Corsair memory
    Realtek RTL8168C(P) gigabit NIC (on board)
    3 X 160 gig SATA II configured in RAID 0
    Fedora 10

    2) Samba server

    2 x Intel P4 Xeon
    4 gig Samsung ecc ddr 266
    Intel 82546EB gigabit NIC (on board)
    2 x 500 gig ide in raid 1 on a 3ware 7410-4 controller
    1 x 500 gig sata
    CentOS 5.2

    (yes, yes, I know about the drive, that's why I am doing the back up, so I can rebuild with 4 X 500 gig IDE in RAID 5)

    3) dump server

    2 x PIII 1000
    4 gig ecc sdram
    Realtek RTL8111 giabit NIC (PCI card)
    700 gig jbod array
    CentOS 5.3

    Does anyone have any suggestions where I should start looking first?

    First check to see that your CAT5 cables support gigabit - long CAT5 cables degrade and so usually cut back to 100mbps (or 10mbps in some cases) - due to errors.

    Are you sure its just happens in scp and samba, try file transfer with FTP/HTTP or NFS
