    Jumbo frames issue in a mixed network

    Tomorrow I should receive the odds and ends that will complete the high
    speed side of my little network. I was considering running these in
    Jumbo Frame (JF).



    Cable-Modem ------- Router That's a 10/100 link
    | |
    10/100 | +---- Printer 10/100
    |
    Switch
    | | |
    | | +-----Mac
    | |
    | +-------PC
    |
    +----------NAS


    Everything "south" of the switch will be 1000 Mbps.

    If I set the Mac, the PC and NAS to JF, will the Printer and Cable-Modem
    work correctly? they cannot be set to JF.

    Thanks.

    Update - seems to work. But Apple Mail and Thunderbird (Mac) don't work
    with JF active. Back to standard frames.

    Too bad - did increase Mac to PC and VV xfer rates by about 10%.

    WHat do you think the average exchange rate of a hard drive is ?
    not pulsed but average ?

    That depends on many things, including the file sizes. Once a large
    file begins streaming, I'd _hope_ for at least 50% of SATA 3 Gb/s. But
    it seems far from that - more like 5 - 6%. (7200 RPM).

    To take disk issues out of the equation, I wrote a program on the PC to
    write to a RAM disk on the MAC. That got me up to a mere 35 MB/s or so
    (occasional bursts of 45 MB/s). I used large blocks in the "write"
    (32768 bytes) to make sure the outbound queue was saturated at all times.

    I suggest you do some reading about the std sata/ide drive transfer
    rates . stripe some of you really need a faster speed

    Striping does not fit other goals.

    Not at all. Real world problems cannot be solved by extremes.

    That's not what you failed to understand but are incapable of understanding.
