    Talking Tweak Test Results

    Lobo wanted to see my tweak test here it is:

    TCP options string = 0204059c01010402

    MTU = 1476

    MTU is not at an optimal value... Consider increasing your MTU to 1500 for optimal throughput.

    MSS = 1436

    Maximum useful data in each packet = 1436, which seems to be equal to MSS.

    MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

    Default Receive Window (RWIN) = 63184
    RWIN Scaling (RFC1323) = 0 bits
    Unscaled Receive Window = 63184

    RWIN is a multiple of MSS
    Other values for RWIN that might work well with your current MTU/MSS:
    252736 (MSS x 44 * scale factor of 4)
    189552 (MSS x 44 * scale factor of 3)
    126368 (MSS x 44 * scale factor of 2)
    63184 (MSS x 44)

    bandwidth * delay product:

    Your RcvWindow limits you to: 5054.72 kbps (631.84 KBytes/s) @ 100ms
    Your RcvWindow limits you to: 2527.36 kbps (315.92 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 1010.944 kbps (126.368 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = true

    Time to live = 245 hops

    Timestamps (RFC1323) = false

    Selective Acknowledgements (RFC2018) = true

    IP type of service = x

    Hmm... Is QoS of 111 the best ?
