Anyone tried this tweak for DSL?

Good, bad or indifferent?

If you try it make sure you backup registry prior to doing so in case your not happy with it, how to backup registry on help page below in sig :) :)

I'll try it and let ya know :)

This is the Windows 98 512 or slower one.. it seems to have removed my MS vtcp386 fix.. not good..

MTU = 1492
MTU seems to be optimized for PPPoE... If you are not on a PPPoE connection, consider increasing your MTU to 1500 for optimal throughput.

MSS = 1452
Maximum useful data in each packet = 1452, which is equal to MSS.
MSS is optimized for PPPoE. If you are not on a PPPoE connection, consider increasing your MTU value.

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:
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:
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 = 52 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

Same exact results for the 768 and faster.. they suck.. no speed increase... just decrease.. I suggest sticking with Speedguide's and CableNut's adjuster. I'm restoring back to those right now. Later.

It's up to you

back to my previous settings...
TCP options string = 020405ac0103030301010402

MTU = 1492
MTU seems to be optimized for PPPoE... If you are not on a PPPoE connection, consider increasing your MTU to 1500 for optimal throughput.

MSS = 1452

MSS is optimized for PPPoE. If you are not on a PPPoE connection, consider increasing your MTU value.

Default Receive Window (RWIN) = 447216
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 55902
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:

TTL value is ok.

Selective Acknowledgements (RFC2018) = ON
All that proggy did was change the RWIN to 383328 for the 768 and faster, and to 255552 for the 512 and slower. Also changes the TTL to 64. Yeuik :eek: Also disables the fix.. which sucks! Or maybe it just turns Tcp1312Opts to 0... oh well.. I suggest to just leave it alone.. just my opinion... :D

Evil if you keep playing with that registry it will be so fragmented (You will lose performance). Your defrag that comes with Windows just defrags your Hard drive, not registry, I got one I bought, I dont know if there's a free one out there or not :)

Steven and Evil them patch's have some problems I have tryed them in the past win98 and Win2k the ones for Win2k I had to restore the registry completely not just the normal copy back to.. I won't touch them again till they come up with a better way of doing there settings
