PENTIUM 4 AT 1.8 WITH 256K
SPEADSTREAM 4060 DSL MODEM
DSL AT 768\128 BUT CAN ONLY GET 635\70.
ANY TWEAKS TO GET A BETTER #.
OS:WIN-ME
TCP options string = 02040586010303040101080a000000000000000001010402
MTU = 1454
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1414
Maximum useful data in each packet = 1402, which is less than MSS because of Timestamps, or other TCP/IP options used.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
Default Receive Window (RWIN) = 531440
RWIN Scaling (RFC1323) = 4 bits
Unscaled Receive Window = 33215
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
520352 (MSS x 46 * scale factor of 8)
260176 (MSS x 46 * scale factor of 4)
130088 (MSS x 46 * scale factor of 2)
65044 (MSS x 46)
bandwidth * delay product:
Your RcvWindow limits you to: 21257.6 kbps (2657.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8503.04 kbps (1062.88 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = OFF
Time to live left = 54 hops
TTL value is ok.
Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
