CP properties for IP = xx.xx.xxx.xx ()
Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.1) Gecko/20060111 Firefox/1.5.0.1
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405b4
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 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 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
MTU Discovery (RFC1191) = ON
Time to live left = 118 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = OFF
IP type of service field (RFC1349) = 00000000 (0)
Operating System - Windows XP Pro + SP2
Any Help will be appreciated, thanks!:thumb:
EDIT:: I will be upgraded to Blueyonder 10MB/384 before the 15th March
