I managed to calculate my RWIN maually as described in msnosteels tips.

(Cap 960 x 124ms)/8 = 14880

14880 /1440 (MSS) = 10.3333333333 or 10

14880 *10 = 148800 is Optimal RWIN.


My question is where exactly do I place this value under Cablenut? I've placed in the Default Receive Window, however, whenever I a TCP anaylzer test, this shows up:

Default Receive Window (RWIN) = 31680
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 31680

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)


it shows my RWIN as 31680???


How come

p.s I've also rebooted to affect the changes.

thanx.

Tcp window size and globabal max tcp windowsize is where you put the new vaules
