TCP options string = 020405b401010402
 
MTU = 1500
MTU is fully optimized for broadband.
 
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
 
Default TCP Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 65535

Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535). Windows 9x might also need the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
 64240 (MSS x 44)
 
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2621.4 Kbps (327.675 KBytes/s) @ 200ms
Your TCP Window limits you to: 1048.56 Kbps (131.07 KBytes/s) @ 500ms
