First of all I stumbled upon this discussion board about 3 weeks ago and have found some interseting resources that I never knew existed. I have had cable internet for about a year now (@home network) and am looking to getting the most out of it.

Here are my system specs: Windows 98SE on a PIII 667mhz with 256MB RAM

I have all the @home installed software, but have disabled the Tioga spyware at startup. I currently use the Proxy server that I am routed through.

I have run a speed test at hxxp://www.speedtest.net/ and here are my results: 5MB download (5242880 bytes, 19500 milliseconds, 2.051 Mbps); 1MB upload (1048576 bytes, 9770 milliseconds, 0.819 Mbps)

Here is the info from the SG TCP/IP analyzer (these results are with the proxy server disabled):

TCP properties for IP = xx.xx.xxx.xx
Note: Read the FAQ if the above is not your IP address.
Browser/OS = Mozilla/4.0 (compatible; MSIE 5.5; Windows 98; AtHome0107)

TCP options string = 020405b4010303040101080a000000000000000001010402

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) = 554800
RWIN Scaling (RFC1323) = 4 bits
Unscaled Receive Window = 34675
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: 22192 kbps (2774 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8876.8 kbps (1109.6 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 46 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

Any input would be much appreciated.

Timestamps need to be off:)
