Hi guys.

I just recently upgraded to the new Kingston Communications Karoo BB service, 8mbps and am looking into maximizing my speed.

The only real changes I have made so far is upgrading my Netgear DG834G router to the latest firmware as i'm worried about messing things up.

Here are my current details.

TCP options string = 0204058a01010402

MTU = 1458
MTU is not fully optimized for broadband. 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 = 1418
Maximum useful data in each packet = 1418, 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). Windows 9x might also need the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
521824 (MSS x 46 * scale factor of 8)
260912 (MSS x 46 * scale factor of 4)
130456 (MSS x 46 * scale factor of 2)
65228 (MSS x 46)

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

Your TCP Window limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your TCP Window limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 117 hops
TTL value is ok.

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

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



Any help would be great!

Thanks in advance.
