    Question older pc win95 Please help review my tweaks

    Long story short see my post #30 if you are on an old system/OS and having problems with TCP Optimizer, RWin and scaling...

    http://forums.speedguide.net/showpos...8&postcount=30

    Hope it Helps

    as Andrzej noted http://forums.speedguide.net/showpos...6&postcount=10 the problem I experienced may have been a problem unique to version 2.0.1 or is it 2.0.2.2 whatever

    ==============================

    Long post, skip to III. below to see my request for help.

    I. My Answers to the initial request for help questions:

    roadrunner cable connection - advertised speed down (dwn 5Megabytes, up = 384Kbs)
    OS = Win95 (unbelievable I know but gets the job done 4 me)
    other: Router, proxomitron & Kerio software firewall

    TCP/IP Analyzer Test now:

    TCPIP analyzer (bypass proxo soft firewall disabled router engaged)

    Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows 95) Opera 7.23 [en]
    Notes: Read the Analyzer FAQ if the above is not your IP address.
    TCP options string = 020405b4010303030101080a000000000000000001010402
    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 (scale factor of 6)
    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 (Note this is not a speed test):

    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 = 46 hops

    TTL value is ok.
    Timestamps (RFC1323) =

    Timestamps (RFC1323) = ON
    Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 00000000 (0)

    ==============================

    II. Tweaking done so far:

    I used TCP Optimizer and selected optimal settings button which changed among other things my RWin from 8760 to 513920 (see below for actual registry changes) and I made some Network connection type changes to Opera web browser


    ==========================

    III. Purpose of my request for help

    To start I want to say thanks for all the great work you all do here.

    The purpose of this post is:

    1) to determine if I should do further tweaking or leave the tweaked settings as they are.

    2) Also I have some specific questions regarding results of UCSC network diagnostic tool,

    3) and a question concerning win95 and application of the faster web browsing tip & forward buffer memory tweak.

    ============

    First Q - is any further tweaking needed to either reach greater speed and/or better connection results, such as turning off time stamp if so how? or dropping the Rwin back to 256960 from 513920

    Second Q My results at UCSC network diagnostic tool http://nitro.ucsc.edu/ (actual results posted under Item IV. below)

    indicate the following:
    1) packet retransmits
    2) duplicate acks received
    3) round trip time is greater now than before tweak
    4) connection stall

    Before tweaking I got none of this. Why now after the tweak am I getting packet retransmits and why the duplicate acks; why the connection stall - do I need to change any settings?

    Also the round trip before the tweak was 71.01 msec now after tweak it is 141 to 166 msec - if my connection is faster shouldn't this number be lower after the tweak?

    Also prior to the tweak this test indicated a recommend Rwin of 26 or 26.7Kbs which would be comparable to TCPIP analyzer's second recommended Rwin of 256960 (MSS x 44 * scale factor of 4). The question here is should I leave it at 513920 or try the lower number (256960) for RWin

    at the end of this post you will see my stats on this test

    Third, I saw the great post here by Dr Tweak: http://forums.speedguide.net/showthread.php?t=73799

    My question is regarding the page load speedup recommendation for win98 and above.

    The question is should I try this tweak on Win95 - in other words are there any known problems with changing priority in the keys referenced for DNS etc. or was it simply omitted on purpose or otherwise.

    My keys are showing:

    DNS priority set to 07 00 00 00
    HostsPriority = 06 00 00 00
    LocalPriority = 05 00 00 00
    NetbtPriority = 08 00 00 00

    for win95 is it ok to set these to 01 00 00 00 without any issues or problems ensuing

    Same question for the FORWARD BUFFER MEMORY TWEAK: I searched but could not find this specific key in my registry so unless you say otherwise I will presume it is not applicable for win95.

    _____________________________________

    IV. Additional info., settings changed or tweaked; UCSC Network analysis results; speed test results after tweaking

    registry settings changed by TCP Optimizer:

    after tweak:

    Rwin 513920
    PMTU 1
    PMTU blackhole 0
    default TTL 64
    Max connections service 10
    Max connections OS 10
    Max MTU 1500
    IP MTU 1500

    before these values were either not set or set to default such as the Rwin was at 8760

    _______________________________________

    additional changes: Browser Opera under network prefs I changed max connection to server to 8 from 4 and Max total connections to 8 from 16

    lower your rwin it's kinda high

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

    check - custom settings
    network adapter selection -
    check modify all adapters
    maxmtu 1500
    TTL - 64
    TCP Receive Window 128480
    MTU Discovery - yes
    Black Hole Detect - no
    Selective Acks - yes
    Max Dup ACKs - 2
    TCP 1323 windows scailing 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 http://beam.to/spybotsd & Ad Aware 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

    mccoffee, et al

    Thanks for your reply - a few Questions

    Lan Browsing Speedup - optimized
    Then select "Apply Changes" and reboot to take effect.
    using tcp optimizer when I change Rwin to 128480 it comes back and says it is not an acceptable value with min = 0 & max = 65535

    I can use 64240, but see below on TCP scaling - must be a quirk in win95 or maybe no registry entry for this?

    should I dump TCP optimizer for DrTCP? If so should I use version 021 or 014

    also Selective Acks, Max Dup Acks, & TCP 1323 windows scaling & timestamp are greyed out which probably explains why the Rwin is set so high if scaling is not available - maybe?


    2. Open IE and select tools - internet options - connections -
    LAN settings, make sure NOTHING there is checked.
    I do not use IE that much (2x a yr if that) but when I do I always connect via local proxy - proxomitron

    this is the only entry there localhost & the port for proxo


    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.
    OK, Im using a router & connected via ethernet adapter

    7. Make sure you do the faster web page tweak in Read1st link.
    So you confirm there are no known issues for win95 in changing my priority settings to 01 00 00 00

    from:

    DNS priority set to 07 00 00 00
    HostsPriority = 06 00 00 00
    LocalPriority = 05 00 00 00
    NetbtPriority = 08 00 00 00

    http://www.speedguide.net/files/W95ws2setup.exe download this patch it should fix the 65536 problem with 95 i can't confirm or deny it why i haven't tested it on a 95 machine before to be honest with you but since i know it works in win98 in theory you shouldn't have any problems doing that tweak try this reg patch that puts those values in http://j79zlr.com/reg/ME98Internet.reg

    mccoffee,

    thanks for the reply.

    I already have ws2update installed; the problem may be in the architecture of win95 not having the scaling

    So am I dead in the water now? or would you go for lowering to 64240 to relieve - I guess I could just try it and see what happens.

    Also probably do the same thing on page load tweak priority codes - the keys are already there - just need to change value to 01 hex...

    always good to backup reg before making changes like this...

    _______________

    If you or anyone else has any additional ideas, please post...

    I guess the thing which caught your eye was the high rwin, but in the context of no scaling avail for me...

    and also the dup acks - I wonder how much this is a drag on my system?

    If you didn't have scailing you would've have rwin as 513920 which is odd since that requires scailing in order to work also if you noticed my reply i said try 128480 with scailing did you reboot after changes???

    The dup acks are fine

    good point on scaling...

    I noticed, but if scaling is greyed out and as noted I tried 128480 but TCP Opt. cited the error as noted in my prior post, it is not an option for me at least from where I am now using TCP opt. Maybe what I need to do is revert back, reboot and then try the custom settings. I'm thinking this will not work either since I searched my registry for anything 1323 and saw nothing associated with TCP options - again maybe a quirk with win95.

    if dup acks is not a problem and no packet loss - & I am over 90% of advertised speed - do I have addtl speed tweak issues if rwin is scaled too big? I think the answer we come up with is yes since I am getting an intermittent packet loss as noted in my 1st post using UCSC network analyzer so I'll try the reverting... or other suggestions as they come...

    Also I was thinking the issue is not how big the straw is if no packet loss (not the case), but rather the number of connections which maybe too many at 10 - is that something to consider? I guess not if you are suggesting to move to 20 for one of the settings from 10...

    ___________

    also maybe I need to try drtcp instead... although I like the tcp opt. maybe it does not like my system?

Maybe what I need to do is revert back, reboot and then try the custom settings. I'm thinking this will not work either since I searched my registry for anything 1323 and saw nothing associated with TCP options - again maybe a quirk with win95.

    if dup acks is not a problem and no packet loss - & I am over 90% of advertised speed - do I have addtl speed tweak issues if rwin is scaled too big? I think the answer we come up with is yes since I am getting an intermittent packet loss as noted in my 1st post using UCSC network analyzer so I'll try the reverting... or other suggestions as they come...

    As I mentioned earlier I do not have this registry entry.

    Are you suggesting I create this?

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip

    Under my \Services

    there is no folder for Tcpip or anything close to that.

    I already read all that before I posted this new thread.

    can someone answer my question...

    The question is for Win95 is it ok (no known negative issues) to add the folder \Tcpip and the proper values to Control RFC 1323

    The link provided by mccoffee:

    http://www.winguides.com/registry/display.php/896

    clearly refereces (Windows NT/2000/XP)

    not all windows and not specifically win95...

    a yes or no will do - but if there are issue specifically for win95 and this registry entry, I would like to know before proceding TIA

    For Windows 9X, make sure you have the latest Dial Up Networking installed, upgrades the TCP stack.
    DUN 1.4
    http://support.microsoft.com/default...;EN-US;q285189

    Also get the vtcp.386 fix from our website.

    mccoffee,

    thank you for the win95 link: http://www.hakanozerdem.biz/registr.../detail-745.htm

    ======

    YeOldeStonecat,

    thank you for that additional info regarding dun upgrade (I have dun1.3 but not the dun 1.4 upgrade) One question - If I am not using dialup why do I need the dun 1.4 upgrade? You said it upgrades the TCP stack?

    I tried to answer my Dun 1.4 question for win95 using this ref:

    http://support.microsoft.com/kb/297774/EN-US/

    What I get is from this link is for Dialup Networking or DUN you get 1) greater security 2) Yr 2000 fix for the DHCP Client 3) PTP or VPN support ; also Name Resolution Issues fixes; Packet Size Adjustment for dial-up connections...

    ....for dial-up - but I still don't get what this has to do with my cable access via ethernet. If someone else can help me understand why I need this dun1.4 upgrade I would appreciate it.

    http://support.microsoft.com/kb/311215/EN-US/ <--- more info

    http://support.microsoft.com/kb/285189/EN-US/ <--- link to dun 1.4

    Thnks also for the ref to the vtcp.386 fix

    In some of my searches, researching this prior to posting this thread I remember reading something about this vtcp.386 fix - now I know I need it and that it is available at this site here:

    http://www.speedguide.net/downloads.php

    ____________________

    Correct me if I'm wrong guys but it sounds like I need to:

    1) use TCP Optimizer to revert back to my original untweaked settings.
    2) Install the dun 1.4 upgrade (after I understand why I need it)
    3) Install the vtcp.386 (after I understand the issues in this fix)
    4) add registry key & values to Control RFC 1323
    5) run TCP Optimizer again - custom install settings suggested by mccoffee in his 1st response post #2

    also can someone tell me how to stay logged in - I checked under user cp and did not see a control set for time out

    wME not possible to use at all - vvvvv slow; vga problems; not posible to tweak
    patience is a virtue ;0

    good info thou - thnks it lets me know I have an uphill fight...

    I'm not dropping packets anymore speeds faster than ever - hit 4.75Mbps out of advertised 5 Mbps page load is faster with page load tweak priority 1, but theoretically according to tcp/ip analyzer scaling is off... and I should only be limited to

    (Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms)

    i know - not a speed test

    my new registry key set scaling on - LOL and I have vtcp386 installed - which explains why my packet problem is no longer an issue...

    [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP]
    Name: Tcp1323Opts
    Type: REG_DWORD (DWORD Value)
    Value: 1 0x00000001 (1)

    also tcp optimizer is having problems interacting with my system

    so my choice was 65k 256k(by screwing with the speed slider) or 513k

    so far I have gotten better performance out of rwin = 513920 no scaling which is 65535 max rwin w/out scaling

    I might scale this back manually using regedit if I discover I am dropping packets again since TCPO won't let me go to 128k.

    still experimenting...
    ___________________

    Has anyone ever gotten win95 & tcpO to work perfectly - i doubt it

    but sure feels good @ close to 5Mbps

    maybe if I do the dun1.4 upgrade I'll hit 5Mbps
