    Angry Bad Upload speed.

    I recently got the tweaks for win xp and did the tcp/ip analyzer
    here are the results.
    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 Receive Window (RWIN) = 513920
    RWIN Scaling (RFC1323) = 3 bits
    Unscaled Receive Window = 64240
    RWIN is a multiple of MSS
    Other values for RWIN that might work well with your current MTU/MSS:
    256960 (MSS x 44 * scale factor of 4)
    128480 (MSS x 44 * scale factor of 2)
    64240 (MSS x 44)

    bandwidth * delay product:
    Your RcvWindow limits you to: 20556.8 kbps (2569.6 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 8222.72 kbps (1027.84 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = ON

    Time to live left = 50 hops
    TTL value is ok.

    Timestamps (RFC1323) = OFF

    Selective Acknowledgements (RFC2018) = ON

    IP type of service field (RFC1349)= 00000000

    My download speed is pretty good, any idea on how to get the upload up to satisfactory?
