Topic: Just want my bandwidth Faster

[_miller_]

Here is my tcp/ip analyzer results, if you can, tell me what i should put in for the program.

TCP options string = 020405b401010402010303000101080a1799848700000000

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.

Default Receive Window (RWIN) = 32768
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 32768
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 1310.72 kbps (163.84 KBytes/s) @ 200ms
Your RcvWindow limits you to: 524.288 kbps (65.536 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 59 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



Thanx

Welcome to the forums , what are your ISP's caps?

[_miller_]

hmmmi could not tell u, but i usualyy get good dl speeds,
ive reacked over 450kbs, and usually get 150 - 300kbs from good websites, and on irc i usually upload at over 100kb/s, sorry i could not tell u the caps, hope this helps you!

OK then who is your Internet Service Provider? I know most ISPs caps.
