TCP properties for IP = ()
Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405b40103030301010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 512000
RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
Unscaled Receive Window = 64000

For optimum performance, consider changing RWIN to 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 (Note this is not a speed test):

Your RcvWindow limits you to: 20480 kbps (2560 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8192 kbps (1024 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 49 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000
