SpeedGuide.net TCP/IP Analyzer
Browser/OS = Mozilla/4.0 (compatible; MSIE 5.01; Windows 98)

TCP options string = 020405b00103030301010402

MTU = 1496
MTU is fully optimized for broadband.

MSS = 1456
Maximum useful data in each packet = 1456, which is equal to MSS.

Default Receive Window (RWIN) = 512512
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 64064
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
256256 (MSS x 44 * scale factor of 4)
128128 (MSS x 44 * scale factor of 2)
64064 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 20500.48 kbps (2562.56 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8200.192 kbps (1025.024 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 19 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

this is how i look now Im running windows 98SE capped @128up /and unlimited down 511MB(memory) I DO GAMING A LOT what RWIN do you guys recomend (cablenut 4.0 running)



thanks

Most games use the UDP protocol to allow online play. RWIN'S and such don't matter because these are TCP protocol options we tweak.

Since 99% of the time your big bad RWIN over 64240 isn't being used any one of the below RWIN's would be optimal:

128128 (MSS x 44 * scale factor of 2)
64064 (MSS x 44)

Cablenut what about an RWIN for downloading i also do a lot of downloading

[cablenut]

We'll can you tell me your average download bandwidth achieved?

[latin]

i think it was 600kb/sec

[cablenut]

Sorry to tell you that if you have a 128bit cap on your upload stream your down stream is capped at or around 315~kBytes

[cablenut]

64064 RWIN

Rwin Limit @ 50ms
1281kB
Rwin Limit @ 100ms
640kB
Rwin Limit @ 150ms
427kB
Rwin Limit @ 200ms
320kB
Rwin Limit @ 250ms
256kB

This looks like a good RWIN for you.

don't know if you caught this or not latin but..........

just thought I would point it out to ya

thanks cablenut u really helpfull im using 64064 its works the best and somehow it keep my ping numer(gaming) under 40 or sometimes 50 IM really happy thsnk you sir!!
