Yep, Impulse is smokin' fast!  On my Comcast connection, I average anywhere from 800KB/sec to 1.5MB/sec.   

They do. This is an accurate video.

What I primarily notice with Impulse is how glacial patch downloads are in comparison to a full game archive. When I install a game from scratch I get a steady 10 Megabytes per second, allowing me to download a big game in a couple of minutes, which is as it should be.

However, whenever a patch is released, the download speed is about 200 KB/sec, a mere 2% of the full game download speed. While I understand the reason for this behaviour, only the full game archives are mirrored to the fast servers, it does result in the rather odd effect that if a patch is large, it is faster to reinstall the game than to patch it. Now, most patches are not that large, so it generally isn't a problem, but it still one of the less impressive parts of the Impulse download experience.

Now if only my connection speed could keep up with Impulse...

I'd love to see someonedo a comparison. I know I get th absolute fastest DL speeds from Impulse (generally around 1.2 to 1.5 MB/s). Some of those other 'services' are pathetically slow.

Same here.... average d/l speeds around 150 - 160kbs on a 1500 connection.  I did have a faster DSL2 connection, but it was $20.00 a month more and downloads were not a lot faster, if at all in some cases... possibly due to ISP server and/or area restrictions, so I cut back to save money on sonething I wasn't actually seeing the benefit of.

I am switching ISP's in Feb 2010... to a 6Mbps connection for 30 bucks less than I'm paying now.  Hopefully then I'll see the blistering speeds others here are seeing.

Impulse does NOW.  But it didn't always.  It behaved VERY throttled until recently.  Kudos to Stardock for opening the server/ISP spigot.  8)

Download Speed: 2881 kbps (360.1 KB/sec transfer rate) that is about what i get anytime i run a speed test on my connection and what it should top out at according to what I pay for but anytime I'm downloading through Impulse I notice it showing download speeds usually between 450KB/sec and 500KB/sec.

So yeah Impulse. 

My first ISP was [eventually] a 56k dialup which was unlimited...as long as you paid the rate....$2 per hour.

That DL would cost $192 ....and thus be totally impractical.

Biggest DL I ever did on that dialup was SP1 of XP ...about 80 meg.

Yep, that's one of the things I like in Impulse, it's always maxing out my download speed . Unlike Steam.

Patches are usually an archive (one file), unless it's game specific. I am usually maxed out with any downloads from impulse, be it full games or just patches.

In most cases Impulse uses my full connection for downloads with somewhere around 1.4MB/s.

I have an 100/100 Mbit connection too, and downloading Demigod is indeed faster than extracting it. But do you also have the problem that some games do not download fast at all?
