    Exclamation Optimization!

    ok ummm I need to optimize my connection settings can someone please help...

    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) = 261804
    RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
    Unscaled Receive Window = 65451

    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: 10472.16 kbps (1309.02 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 4188.864 kbps (523.608 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = ON
    Time to live left = 57 hops

    TTL value is ok.

    Timestamps (RFC1323) = OFF

    Selective Acknowledgements (RFC2018) = ON

    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

    ok this is the results from the analyser can someone please tell me how to tweak my connection it is 512k/256k...the one thing i cant find is how to change my RWIN to a Multiple MSS. thx

    Try thease in the sg optmizer below me to download and install

    select - cable
    check - custom settings
    network adapter selection -
    check modify all adapters
    maxmtu -1500
    TTL - 64
    TCP Receive Window6 32768
    MTU Discovery - yes
    Black Hole Detect - no
    Selective Acks - yes
    Max Dup ACKs - 2
    TCP 1323 nothing is checked

    Other Settings tab:

    Max Connections per Server - 10
    Max Connections per 1.0 Server - 20
    Lan Browsing Speedup - optimized

    Then select "Apply Changes" and reboot to take effect.



    1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.



    2. Open IE and select tools - internet options - connections -

    LAN settings, make sure NOTHING there is checked.



    3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.



    4. Clear your temporary internet files.



    5. Power cycle your modem, unplug it for atleast 15 seconds.



    6. Download and update then do a scan with SpyBot 1.2 http://beam.to/spybotsd & Ad Aware 6.0 http://www.lavasoftusa.com/support/download to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.



    7. Make sure you do the faster web page tweak in Read1st link.



    8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com for further instructions on removing it's left over junk.



    9. Install Outpost Firewall http://www.agnitum.com\ or Sygate Firewall http://www.sygate.com/ , both have FREE and Pro versions and are heads above ZA.



    10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, AVG 6.0 http://www.grisoft.com/us/us_dwnl_free.php is an excellent FREE AV app.



    11. Make sure you have ALL of the latest Windows Updates
