Can I use Speedguides optimizer with my Cablenut settings,or is that over kill?
xp,512ddr,1.4tbird,comcast

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 Receive Window (RWIN) = 51100
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 51100
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)
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: 2044 kbps (255.5 KBytes/s) @ 200ms
Your RcvWindow limits you to: 817.6 kbps (102.2 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 23 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 11111110
Precedence (priority) = 111 (Network Control)
Delay = 1 (low delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 1 (low cost)

Cablenut will overwrite anything else, besides you only need one or the other.

How is your speed? You might try RWINs of 17520/23360/27740/36500/55480/93440 but if your speed is great now leave it alone.

Im confused,is this close to my caps at all or am i getting screwed?Im thinking of going with Knology cable here soon.

Communications

1.3 megabits per second
How communication devices are rated. Kilo means 1,000 and mega means 1,000,000. Examples include 56k modem and 10Mbit Ethernet

Storage
164.6 kilobytes per second
The way data is measured on your hard drive and how FTP programs measure transfer speeds. Kilo is 1,024 and mega is 1,048,576.
1MB file download

6.2 seconds
The time it would take you to download a 1 megabyte file at this speed.

Your download speed : 1391423 bps, or 1391 kbps.
A 169.8 KB/sec transfer rate.
Your upload speed : 62126 bps, or 62 kbps.
Seems like broadband .. above the 1mbit barrier!

That is very good, you are getting about 1400 down with a 1500 cap.
