Not getting advertised speeds when using testmy.net speedtest

[Iceman0803]

I've switched back to Cox Communications from Centurylink and I can't seem to get anywhere close to my rated speeds using the testmy.net speed test. In fact, as I posted in another thread, my results even vary between browsers on the same system. I'm subscribed to cox's Ultimate tier which is supposed to give me speeds of 65Mb down and 5Mb up. The following are my results from testmy.net using a custom test size of 100MB With Firefox, Chrome, and IE9:

I have no malware/viruses on my system and I ran the tests with avast shields on and off with no differences. I ran dslreports tcp optimizer and everything looks good except for RWIN values. But, I can't change them being that Win 7 auto tunes those values depending on connection conditions. [size=4]http://www.dslreport...ista&via=normal[/size]

Run a few tests from the east as well as west coast servers and post please, Your ISP may have peering issues, or there could be something else slowing the connection down to the central server.

I didn't bother calculating the averages this time around because I couldn't complete the test on a couple of runs.

Also, when I run the test here http://nitro.ucsc.edu/ my results are 34.29Mb/s down and 5.96Mb/s up and I get a message that "Other network traffic is congesting the link." I don't think the network traffic they're referring to is local to me because I've disconnected all other wired clients and disabled wireless for the purposes of testing.

I might do a few traceroutes, find where your getting bounced around through.
