said by ualdayan:Guys, guys, calm down. Powerboost is still there. It's the speedtest.comcast.net that's changed. (And it changed awhile back, not as part of these changes). It downloads/uploads for longer and that means a larger percentage of the test happens at non powerboosted speeds - therefore it reports a lower result. A phone/tablet maxing out a WiFi connection at optimal conditions can still result in a very high Mbps speedtest because they haven't changed the app on mobile devices to use the larger data payload that the website based ones do.
In their defense, ShaperProbe numbers were posted earlier, which splits the PB/non-PB results.
As for the Comcast test, in my recent experience, it still greatly skews results towards best-case PB speeds. I just ran a test a couple of minutes ago and hit 75 Mbps down, before dropping to 23 at about 80% through it. It reported 67.2 Mbps down at the end of it. I suppose that's understandable considering it dropped off near the end of it. However, it reported 22.36 Mbps up, even though my upstream PB ran out at about 40% through that part of the test and dropped to 5 Mbps for the rest of it.
I typically use the Comcast speedtest to check for local/regional congestion (and e-peen numbers
), and ShaperProbe to check for provisioning and sustained throughput. Sometimes I also do an FTP upload to my website to check sustained upstream speeds.
While I find the variance in PB reported earlier to be odd/interesting (ex. ropeguru
's results are pretty close to residential Blast PB), I wouldn't mind it much myself if it got reduced. I was on 50/10 until mid-August, and I didn't mind the complete lack of it there.
