[glow=red,2,300]whitch scale factor 4  and scale factor 8 here[/glow] 

TCP options string = 020405ac01010402

MTU = 1492

MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.

MSS = 1452

MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.

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:

63888  (up to 2 Mbit lines, depending on latency. MSS * 44)

127776 (1-5 Mbit lines, depending on latency. MSS * 44 * 2)

255552 (2-14 Mbit lines, depending on latency. MSS * 44 * 2^2)

511104 (8-30 Mbit lines, depending on latency. MSS * 44 * 2^3)

1022208 (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 = 107 hops

TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

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

hi im new here thank you testmy.net
