Hello again, I've formated my PC and insalled XP PRO... It basically ownz every other Windows OS I've used (I've tried all of them..)
I'm just tweaking my XP and I want to tweak my DSL (1.5mbs Earthlink) ...
I am using Default WinXP network PPPoe dialer...
TCP options string = 020405a00103030201010402
MTU = 1480
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1440
Maximum useful data in each packet = 1440, which is equal to MSS.
Default Receive Window (RWIN) = 253440
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 63360
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)
bandwidth * delay product:
Your RcvWindow limits you to: 10137.6 kbps (1267.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4055.04 kbps (506.88 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 54 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000

Select connection type at top, select adapter, select custom settings, enter 1 at a time 31680 or 63360, uncheck scaling under Tcp1323Opts, apply changes and REBOOT each time you change number in Optimizer if number Optimizer puts in does not work for you.
