STATISTICHE DA SPEEDGUIDE:----------------------------------
MTU = 1460
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1420
Maximum useful data in each packet = 1420, which equals MSS.
Default TCP Receive Window (RWIN) = 17040
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 17040

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
522560 (MSS x 46 * scale factor of 8)
261280 (MSS x 46 * scale factor of 4)
130640 (MSS x 46 * scale factor of 2)
65320 (MSS x 46)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 682 kbps (85 KBytes/s) @ 200ms
Your TCP Window limits you to: 273 kbps (34 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
