Is this good or What?

[Rolodex]

TCP options string = 020405b40103030301010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 513920
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 20556.8 kbps (2569.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8222.72 kbps (1027.84 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 53 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Can I make work better than this (Windows 2000)?

Any questions or comments are appreciated!

Need system specs, thank you:) :)

Yes test looks fine but you probably can go faster, try these RWIN's 522680, 524176 or 531440 :) :) :)

Here's the next read after using the FIRST set of RWIN's:

Going to test the next set of values ... be right back! :)

Do m a speed test at www.pcpitstop.com and choose RWIN you like best, you do not have to show me tests:)
