The multicast speed is reduced(???)

  • Environment : 120G ssd (SSD) , samsung desktop PCs
    client : 3(PCs)
    gear : 3com 16 Port switch

    As you told me earlier, I've been working on it, adding options and working on it.
    however, An unexpected problem occurred.
    At first I get the speed normally
    The speed drops at the end. (340 M / min)

    [option -> multicast -> --blocksize 700]

    I wonder if there are other options in addition to this option.

    Or I wonder if it is affected by the LAN or other places.

    Do not you have any other suggestions?

    thanks for reading.
