Help me Tweak please
« on: April 08, 2006, 03:18:11 pm »
Im using Verizon DSL Versalink modem.

TCP options string = 020405ac01010402
 
MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
 
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.
 
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:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
 63888 (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 = 120 hops
TTL value is ok.
 
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

Notes: Read the Analyzer FAQ if the above is not your IP address.

TCP options string = 020405a401010402
 
MTU = 1484
MTU is somewhat optimized for broadband. If you're not on a PPPoE DSL connection that limits packet size, consider increasing your MTU to 1500 for optimal throughput.
 
MSS = 1444
Maximum useful data in each packet = 1444, which equals MSS.
 
Default TCP Receive Window (RWIN) = 33396
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 33396

For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
508288 (MSS x 44 * scale factor of 8)
254144 (MSS x 44 * scale factor of 4)
127072 (MSS x 44 * scale factor of 2)
 63536 (MSS x 44)
 
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 1335.84 kbps (166.98 KBytes/s) @ 200ms
Your TCP Window limits you to: 534.336 kbps (66.792 KBytes/s) @ 500ms
 
MTU Discovery (RFC1191) = ON
 
Time to live left = 120 hops
TTL value is ok.
 
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)


That look better?
