Question about my cable co. and speed!

Hi,im not new per say I have visited this site alot, but i decided to sign up, so Hi everyone. I live in New Orleans and my high speed Co. is Cox comunications, well in there website they say this

"Cox High Speed Internet provides you with high-speed Internet access by using hybrid fiber-coaxial cable lines. This high bandwidth solution takes advantage of the capacity of Cox's cable lines and network to overcome many of the bottlenecks that plague typical Internet connections today. The result is a faster, more reliable Internet experience for your home, with upstream data transfer speeds of up to 768 kbps and downstream speeds of up to 5 MB."

What do you think, I have the 4MB down and and 512kbs up package, also can I say this is T1 or not? I have never seen my speed reach 4MB the highest was close to 600kbs. Yea I have tried the tweaks here( O thanks for those great programs, they did improve my speed,haha) I tested the speed here an it says hum 1.66MB but when I go to pcpitstop it tells me close to 4MB, but i have never seen that speed. Can someone please explain. I have 2 pcs connected to a D-LINK DI-604, I have forward ports, I have sygate firewall.(SAY NO TO ZONE ALARM). Sorry for the long post.

Sorry, hum Im running WINXP Home (soon to be pro)

Heres the test results:

CP properties for IP = 68.11.108.50 () *
Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.8 StumbleUpon/1.993
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 64240

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)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 54 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

*Not real Ip address

Your never going to connect at the speed in which speed tests are done... thats just rule of thumb less you have a computer sittin in the next room directly connected. See your download of a file may come from another source much slower in upload speeds such as your own and as you can see upload speeds are much lower than download packages IE: 4m down and 60kup... Also you have to look at the traffic on the net at the time and the hops in which you have to go through to get the file transfer complete and some hops may be very slow depending on traffic downloading the same file or just that the net is jammed up mostly in the evenings. I've got a 11meg down 800k/up speed on my cable with tests done on bandwidthplace and dslreports but I've never seen faster than 800k download speeds and thats on very fast servers less you pay a subscription service like fileplanet perhaps. Best thing to do is follow the tweeking advice on this forum to optimize it but sounds like to me your running pretty good at 600k/down now with a 4/m sec package.

A T1 is 1500 Kbits/s in both directions. As for your connection, is that 600 Kbytes/s or 600 Kbits/s? Big difference. 600 Kbytes = 4800 kbits which would be excellent. 600 Kbits = 75 Kbytes.
