TCP options string = 02040550010303030101080a000000000000000001010402
MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1360
Maximum useful data in each packet = 1348, which is less than MSS because of Timestamps, or other TCP/IP options used.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
Default Receive Window (RWIN) = 522240
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 65280
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
65280 (MSS x 48)
bandwidth * delay product:
Your RcvWindow limits you to: 20889.6 kbps (2611.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8355.84 kbps (1044.48 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 48 hops
TTL value is ok.
Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.
