i am using ADSL router of 256kbps.(nearly 32KB/s).
but when i want to download something it gives me only 8KB/s to 15KB/s and sometimes below 5KB/s
and i am using windows Xp professional SP2
my results with TCP/IP analyzer is
TCP options string = 0204058601010402
MTU = 1454
MTU sometimes used in PPPoA applications. If not, consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1414
Maximum useful data in each packet = 1414, which equals MSS.
Default TCP Receive Window (RWIN) = 16968
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 16968
RWIN is a multiple of MSS
Other RWIN values 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 (Note this is not a speed test):
Your TCP Window limits you to: 678.72 kbps (84.84 KBytes/s) @ 200ms
Your TCP Window limits you to: 271.488 kbps (33.936 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 121 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
plz help me to tweak my speed.thanks in advance
i have new TCP optimizer,what settings i have to do.
