new pc /connection - optimizer settings please

Post by TNATireFryer »

TCP options string = 020405b401010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default TCP Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 65535

Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535).
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
64240 (up to 2 Mbit lines, depending on latency. MSS * 44)
128480 (1-5 Mbit lines, depending on latency. MSS * 44 * 2)
256960 (2-14 Mbit lines, depending on latency. MSS * 44 * 2^2)
513920 (8-30 Mbit lines, depending on latency. MSS * 44 * 2^3)
1027840 (25-60 Mbit lines depending on latency. MSS * 44 * 2^4)

bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2621 kbps (328 KBytes/s) @ 200ms
Your TCP Window limits you to: 1049 kbps (131 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 114 hops
TTL value is ok.

Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000 (0)

thanks for looking if anything is needed

Try the 10mb settings in the optimizer

is this better?
didnt know quite what you ment - so i slid the slider to 10,000- hope thats what you ment -
