Help Me Someone with Rwin

[adamr]

hope this link still works
http://www.broadbandreports.com/tweakr/block:51ae09e?service=dsl&speed=512&os=winXP&via=routerpppoe

The link above is my speed test results, the part im interested in says:"Choose RWIN between 5808 and 13068" ... please someone help give me a value, how do i know which is a good value between 5808 and 13068???

Please help me!! put the info below as well

no one ... !?

no one was killed off a few months ago

Per what I've read on dslreports FAQ your Rwin will be a multiple of your mss, which at 1452 x 4 = 5808 , x6 = 8712 x8 = 11616

Try each.

thanks, messing with the settings, seems like the low values iv tried are causing latency ... good this be the effects of messing with this setting

 

[adamr]

56.4 kbit/s on telkom speed test on a 512 line. Thats ok right?

 

[thedoc!]

yes

from what i learnt on campus

RWIN = recieve window

that is the max number of packets a client can request at any given time,

-the more packets u can request means the more bandwidth u squeezing out of ur connection.

-u cant set this value to something too high and unrealistic cos if u request too many packets in a second those packets that cannot squeeze thro get dropped or delayed causing latency.

-a too low setting means u under utilize the bandwidth available to u.

theres a couple of windows (send window) and stuff that also directly affect the performance of ur line. unless u really know what ure doing u should leave these values untouched. changing one window wont get u the effect u desire, cos all these windows work hand in hand. its alot more complicated than what ive said, so dont flame me for being simplistic

if ull want a full text book explanation i can help, but check out wikipedia ull probably find what ure looking for faster.

thanks... do recall something like that in varsity, will scratch in my data comms books ... thanks dude for the help
