my downloads starts high and ends low

[ematt]

when i download a file my downloads starts at about 400kb/s and by the end of the download it will be about 200kb/s. This is downloading a file of 10MB or more.

Ihave Pentium III, 550MHz, win98se, 128 memory and IE 6.0


is this normal for my system ok can it be tweaked for a more stable download.


MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 43 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Try RWIN (Default Recieve Window of 481800)

my downloads drops down to about 230kb/s now.
is there a limit to how high i can take the (RWIN).
