Re: Is this throttling?

yeah I didnt check to see where i was connecting to with your link.. my bad there.

I think we can all agree that the bottom line is if the connection is healthy, factoring in powerboost, a typical throughput graph (assuming you're testing against a non-overloaded server and you're "dedicating" your connection to the test.. i.e. telling everyone else to stop doing stuff on the net), your graph should start high, fall off some as powerboost stops, then it should be damn near a rock solid straight line for the duration of the download.

i'll try to post up some TCP stream graphs from wireshark, against some hefty sized downloads (via ftp or sftp), that shows this.

I used to do tcp stream graphs, and look at them all the time when i had dsl and i was on exhausted at&t redbacks/BRAS. you would see the graph go ape-shit (up and down up and down), during prime-time hours. not that clean looking saw-tooth pattern (that looks like throttling, kinda-sorta) and certainly not a smooth straight line.
