First I've always used
http://www.speakeasy.net/speedtest/
But the numbers seem to be similiar.
6277 down, 1586 up from speedtest
6038 down, 1583 up from speakeasy
either it's my wireless laptop, or things are busy tonite.
Over the past month I've checked 10 or 15 times, from my wired desktop, and I have been get download speeds more like 15000+ to once or twice > 20k.
Not bad for lowly cable !!!!
