    TCP Optimizer backup files

    Hi I downloaded TCP Optimizer as part of an HP online class. They had us make a backup of our original settings before we ran the program. But after I ran the program I now have two other backup files on my desktop: sg_backup_2006-12-11-1543.spg and first backup.spg. What are these files and do I need to keep them both and the one I made? Thank you very much.

    P.S. If I reset my router do I need to rerun the program? Thanks again.

    The first backup is your original settings. Subsequent backups will be dated filenames.

    After using TCP Optimizer, do the TCP Analyzer to check your new settings to see if your MTU value is of the correct value and if RWIN is a multiple of MSS. Same goes when resetting your router.

    These are my results from the analyzer.

    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 your MTU value.
    Default TCP Receive Window (RWIN) = 257004
    RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
    Unscaled TCP Receive Window = 64251

    RWIN is a multiple of MSS
    Other RWIN values 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 TCP Window limits you to: 10280 kbps (1285 KBytes/s) @ 200ms
    Your TCP Window limits you to: 4112 kbps (514 KBytes/s) @ 500ms
    MTU Discovery (RFC1191) = ON
    Time to live left = 51 hops
    TTL value is ok.
    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 00000000 (0)

    Do I need to restore my original settings and do this again?
    I am on a DSL connection. My ISP advertises my download speed at 3Mbs.
    That is 3000kb, correct?
    Thank you for your help.

    No. You do not need to revert to original settings to use TCP Optimizer again and again. Subsequent dated filenames of backups will be created, with the first backup as your original settings before using TCP Optimizer for the first time.

    Your TCP Receive Window (RWIN) set at 257004 is too high for a 3 mbps bandwidth.

    Use the following custom setting with TCP Optimizer:

    General Settings tab:
    Custom settings - check
    Modify All Network Adapters - check
    network adapter selection - your NIC
    MTU - 1492
    TTL - 64
    TCP Receive Window - 63888
    MTU Discovery - Yes
    Black Hole Detect - No
    Selective Acks - Yes
    Max Duplicate ACKs - 2
    TCP 1323 Options:
    Windows Scaling - uncheck
    Timestamps - uncheck

    Advanced Settings tab:
    Max Connections per Server - 10
    Max Connections per 1.0 Server - 20
    LocalPriority - 5
    Host Priority - 6
    DNSPriority - 7
    NetbtPriority - 8
    Lan Browsing speedup - optimized
    QoS: NonBestEffortLimit - 0
    ToS: DisableUserTOSSetting - 0
    ToS: DefaultTOSValue - 80
    MaxNegativeCacheTtl - 0
    NetFailureCacheTime - 0
    NegativeSOACache Time - 0
    LAN Request Buffer Size - 32768
    Then select "Apply Changes" and reboot to take effect

    Thank you Trogers. I applied the changes you suggested. I am sure it will help.
    I did notice that under MTU there is a check mark in the box for PPoE. I don't have to use a username and password every time I want to go online. I just hit firefox and I'm there. Should this be check still? Thanks again for your help. I am learning a lot from this.

    You are using a router and thus have an 'always-on' connection through the router. But do write down your username and password in a notebook just in case you need to connect directly through your modem to access the internet, eg. when the router is defective.

    The check box under MTU in TCP Optimizer are for those who have a ADSL PPPoE connection, when MTU is 1492, just a convenience. You can also enter an MTU value without using the check box.

    Ok I see. My modem is an ADSL modem so I guess I'll leave it be. Isn't hurting anything.
