TCP options string = 020405b40103030401010402
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) = 578160
RWIN Scaling (RFC1323) = 4 bits
Unscaled Receive Window = 36135
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
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: 23126.4 kbps (2890.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 9250.56 kbps (1156.32 KBytes/s) @ 500ms
