Just recently I noticed that when I try and upload a file from my Shaw home Xtreme account via SSH (scp), the transfer starts out quickly reaching nearly 1Mb, then my entire Shaw connection clamps right down and my ping times shoot through the roof (800ms).
In fact, not only does the upload slow to a crawl but the entire connection becomes unusable for anything.
I don't do a lot of uploading but I don't recall this ever happening before.
Is anyone else seeing this? Has Shaw started some heavy duty traffic shaping?

Just terrible performance on their news servers. Then again they've always treated NNTP as a joke. At this point it could be anything. I had to go back to Feisty from Gutsy (Ubuntu) because of what looks like a driver issue from ATI.

I have not noticed this behaviour with Extreme.
I just now tried a few uploads of a 5M file. It would hit 200KB+ occassionally atr the start but average rate for all 4 uploads was the same 121.3K(even to different hosts). That seems strange and sure sound like rate shaping. If I did concurrent uploads I would get close to the 1Mbps throughput.
I wonder if "Power Boost" applies to uploading? My uploads peaked over 200K which is certainly higher than 1Mbps.

I guess it was just either a local congestion issue or some other temporary Shaw problem.
I Tested it again tonight and got nearly a full megabit upload sustained using the same file as last night.
Glad to say it was a false alarm.
