Please help finding a starting RWIN?

Do you think my RWIN of 16060 is too low? My results are: Receive Window (RWIN): 16060 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: 116

Try running the Tweak Test at this site:

see what it says under Notes and recommendations: at the bottom of the first column. My results look like this:

1. Your Tweakable Settings: Receive Window (RWIN): 64240 Window Scaling: 0 Path MTU Discovery: ON RFC1323 Window Scaling: ON RFC1323 Time Stamping: OFF Selective Acks: ON MSS requested: 1460 TTL: (less any hops behind firewall) 65 TTL remaining: 51 Notes and recommendations: RWIN is in range Looking good

That figure does sound too low to me. What did it say under Notes and recommendations: ? I think that a RWIN of 64240 might be a good one for you. Mac

RWIN is too low !

RWIN = MSS x 44 x SF , where SF=Scale Factor of 1 , 2 or 4

SF=1, RWIN=64240 SF=2, RWIN=128480

I also suggest a *better* utility than DrTCP -- 'TCP Optimizer' from SpeedGuide.Com

Try one of these and see what it suggests for "buffer size":
