hello Mr Helper, i am currently running Win XP Corp. on Pen.4 w/ 1.5Ghz plus 256MB...
DSL info: max d.stream is 60K/s (verizonDSL)...
question!!! is there a way to tweak this DSL for improvement downstream? if possible... below is my current tweak info:
**********************************************
TCP options string = 020405a001010402
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) = 17280
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17280
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)
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)
bandwidth * delay product:
Your RcvWindow limits you to: 691.2 kbps (86.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 276.48 kbps (34.56 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 114 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
Thanks in advanced Mr.
