said by Mactron:Downloading and uploading large files for a few minutes at a time from/to fast sites (like Comcast's web servers or upload FTP area) is a pretty good test.
From the OP at Slashdot..."I know my father is not paying for a 10+ Mbps connection. Is Comcast giving priority to popular speed-test sites?"
The thread appears to have spiraled downward from there.
To bad. I'm no Comcast fanboi but I think Comcast came up with a winner with PowerBoost. Very handy for those patches, updates, small Freeware downloads.
Q for Comcaster's, how do you speed test removing the PowerBoost effect ?
