I have been reading various post in the forum for the past couple of days trying to determine why I cannot get consistent acceptable results from my DSL connection. I have never come close to the expected 90% of my rated speed of service.
Test results show before and after applying Cablenut VanBurens_cablenut_settings_version_8/CABLE_DSL_FIBER_DIAL-UP/WinXP_2K_CABLE_DSL/MTU 1500/1500.ccs
I don't understand 98% of the test result data. Any guidance and help you can give will be greatly appreciated.
TCP options string = 020405b401010402 MTU = 1500
MTU is fully optimized for broadband. MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled 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 values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of
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: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms MTU Discovery (RFC1191) = ON Time to live left = 114 hops
TTL value is ok. Timestamps (RFC1323) = OFF Selective Acknowledgements (RFC2018) = ON IP type of service field (RFC1349) = 00000000 (0)
