doofus Posted March 9, 2003 Share Posted March 9, 2003 Mines set at 13140 for a 512kb broadband connection and wondered if its maybe a little high still, or maybe its a little too low??. I changed it from its default (whatever that was.....lol) so just wondered what others have theres set at thats relevant to my connetion?.

HammerSlammer Posted March 10, 2003 Share Posted March 10, 2003 All depends on whose bandwidth test I use and the time of day. It just seems to be the best setting for me as far as average speeds. Link to comment Share on other sites More sharing options...
dave Posted March 10, 2003 Share Posted March 10, 2003 There is no single best RWIN value. Ideally you want the highest RWIN value you can use. However, if there are any lost packets or retransmissions a high RWIN value hurts because you may have to throw away more data. That will vary for every site you visit. Usually a 64000 or so RWIN value is the highest you need for most home broadband connections. When you said "13140" did you miss a digit there? That is too low for a 512K connection.

franglais Posted March 10, 2003 Share Posted March 10, 2003 Hey Keith....I've tried many RWIN settings on my DSL and the one I use all the time now is 255552, it seems to give the best results, no matter what time of day! Link to comment Share on other sites More sharing options...

Thats the corerct value in the registry that i added instead of the default (whatever that is/was). Seems ok as things go, tho i havnt a clue as regards how it all works. Edit Your Tweakable Settings: Receive Window (RWIN): 13140 Window Scaling: off Path MTU Discovery: ON RFC1323 Window Scaling: OFF RFC1323 Time Stamping: OFF Selective Acks: ON MSS requested: 1460 TTL: unknown TTL remaining: 115 Notes and recommendations: RWIN is in range Looking good Example 146000 byte download Actual data bytes sent: 146000 Actual data packets: 100 Max packet sent (MTU): 1500 Max packet recd (MTU): 1500 Retransmitted data packets: 0 sacks you sent: 0 pushed data pkts: 20 data transmit time: 1.363 secs our max idletime: 161.5 ms transfer rate: 69584 bytes/sec transfer rate: 556 kbits/sec This is not a speed test! transfer efficiency: 100% Those are the latest tests ive done using that 13140 setting.

TorreyIsLDS Posted March 11, 2003 Share Posted March 11, 2003 17520 works for a low sped cable connex like mine, 1MB... you should most preferably set it to that or lower. Link to comment Share on other sites More sharing options...
