tcp/ip settings

[davemw858]

greetings,
im unclear about my rwin setting. registry is set to 256960 but analyzer still reports 65535. i read about the fix but does it apply to win ME as well? and will it make a diff?
thx

TCP options string = 020405b401010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
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: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 115 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Set Tcp1323Opts to 1 :)

lol...ok one more dumb question.....how?

[Lobo]

Do you have Cablenuts adjuster:)

[davemw858]

no i dont....direct me please?
tia

Help page in sig but that means reinstalling all patches but it's worth it, instruction on help page:) :)

[EvilAjax]

CableNut Adjuster is the best! NurseTcp sucks!

Once you do everything on the help page, post your new results . If you're not happy with speed or think you can do better then we can help tweak you! :D

[davemw858]

ok i got the adjuster (hope i did this right). selected my os and applied the settings. but now the analyzer page wont load to post my results. ugh!! i shoulda left it alone lol.

[Lobo]

You did not follow directions on help page as it says nothing about loading any settings, and they must be working on adjuster,
I would follow the directions on help page:) :)

[davemw858]

how does this look? should i turn off the timestamps? seems to be working good.

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.

Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS

MTU Discovery (RFC1191) = ON

Time to live left = 115 hops
TTL value is ok.

Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.

IP type of service field (RFC1349)= 00000000

Set Tcp1323Opts to 1. Everything else looks great! Good job. How are your speeds? Do you think you can do better than what you're doing now?

[davemw858]

speed seems great. this thing flies for an older machine. im impressed. will try what you said though. thx a bunch.

try turning Timestamps off
