    Talking TCP optimizer tweak?

    SpeedGuide.net TCP/IP Analyzer


    TCP properties for IP = ***.***.***.*** ()
    Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)
    Notes: Read the Analyzer FAQ if the above is not your IP address.

    TCP options string = 020405b00103030201010402
    MTU = 1496
    MTU is fully optimized for broadband.
    MSS = 1456
    Maximum useful data in each packet = 1456, which equals MSS.

    Default Receive Window (RWIN) = 256960
    RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
    Unscaled Receive Window = 64240

    For optimum performance, consider changing RWIN to a multiple of MSS.
    Other values for RWIN that might work well with your current MTU/MSS:
    512512 (MSS x 44 * scale factor of 8)
    256256 (MSS x 44 * scale factor of 4)
    128128 (MSS x 44 * scale factor of 2)
    64064 (MSS x 44)
    bandwidth * delay product (Note this is not a speed test):

    Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
    MTU Discovery (RFC1191) = ON
    Time to live left = 53 hops

    TTL value is ok.
    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 00000000 (0)

    Thank for your help~!!!
