    10 mbit / 1 mbit settings?

    Finally got 10mbit/1mbit connection... I've been messing around with the receivewindow and I cant get more than about 7830 kb/s. When I had the 5mbps I was getting about 4850.

    Got any good settings for me?

    Btw forgot my analyzer....

    TCP options string = 020405b40103030301010402
    MTU = 1500
    MTU is fully optimized for broadband.
    MSS = 1460
    Maximum useful data in each packet = 1460, which equals MSS.
    Default TCP Receive Window (RWIN) = 513920
    RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
    Unscaled TCP Receive Window = 64240

    RWIN is a multiple of MSS
    Other RWIN values that might work well with your current MTU/MSS:
    513920 (MSS x 44 * scale factor of 8) <-- current value
    256960 (MSS x 44 * scale factor of 4)
    128480 (MSS x 44 * scale factor of 2)
    64240 (MSS x 44)
    bandwidth * delay product (Note this is not a speed test):

    Your TCP Window limits you to: 20557 kbps (2570 KBytes/s) @ 200ms
    Your TCP Window limits you to: 8223 kbps (1028 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) = 11110000 (240)
    Precedence (priority) = 111 (Network Control)
    Delay = 1 (low delay)
    Throughput = 0 (normal throughput)
    Reliability = 0 (normal reliability)
    Cost = 0 (normal cost)
    Check bit = 0 (correct, 8th checking bit must be zero)

    DiffServ (RFC 2474) = No valid DiffServ equivalent. See the TCP Optimizer documentation, or RFCs 2474, 2475, 2597, 2598, 2873.

    If you are in the US, try a smaller RWIN. Maybe 128480 or 256960.

    Tried both those RWINS, still max about 7400 kbps... on a 10mbit that cant be right can it?

    Do a tracert to www.speedguide.net and check where in your connection ping times may be irregular and causing slow speed.
