    Am I getting value for money from my ISP - speed test result in half speed

    Hi everyone,

    I'd be grateful if someone could analyse my data below and let me know if there is anything I need to tweak in order to get greater performance.

    My ADSL service is with Bulldog at 2Mbps/256Kps (PPPoA)
    I am running Windows XP Pro with SP2

    Using the Speedtest on this site I am getting on average:
    0.913 Mbps (913 kbps, 112 KBps).

    I have followed all the tweak tips and used CableNut to place settings in my registry but no difference is noted.

    TCP/IP Analyzer results below:

    SpeedGuide.net TCP/IP Analyzer

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

    TCP options string = 020405ac0103030201010402
    MTU = 1492
    MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
    MSS = 1452
    MSS is optimized for PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

    Default Receive Window (RWIN) = 256000
    RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
    Unscaled Receive Window = 64000

    For optimum performance, consider changing RWIN to a multiple of MSS.
    Other values for RWIN that might work well with your current MTU/MSS:
    511104 (MSS x 44 * scale factor of 8)
    255552 (MSS x 44 * scale factor of 4)
    127776 (MSS x 44 * scale factor of 2)
    63888 (MSS x 44)
    bandwidth * delay product (Note this is not a speed test):

    Your RcvWindow limits you to: 10240 kbps (1280 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 4096 kbps (512 KBytes/s) @ 500ms
    MTU Discovery (RFC1191) = ON
    Time to live left = 60 hops

    TTL value is ok.
    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 11110000

    Precedence (priority) = 000 (routine)
    Delay = 0 (normal delay)
    Throughput = 1 (high throughput)
    Reliability = 1 (high reliability)
    Cost = 1 (low cost)


    Many thanks
    Luigidon

    Ideally, move your computer closer to the server you are testing with.

    Realistically, your settings are fine. You are getting about what you should expect for a 2 Mbit connection.

    At optimum times (around 2:30 am), my 4Mbit connection is at 3542.

    I wouldn't worry.
