Re: [Speed] Comcast Business Class Speed Upgraded in CaliforniaOh, your salesperson said it. That's shocking. |

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. |

Cannot say that is true here. I do not get the initial burst at all even on the Comcast speedtest. As late as this weekend I was still seeing the high burst rates, 70+/10+, no matter what Comcast test I hit. Additionally, shaper probe is no longer showing the higher burst ratee that I was seeing before. So they have screwed something up when rolling out the speed increases. At least here in this area. Capacity estimation before: Estimating capacity: Upstream: 20946 Kbps. Downstream: 129069 Kbps. Capacity estimation now: Estimating capacity: Upstream: 7700 Kbps. Downstream: 36244 Kbps. |

Hmm, maybe all the business line owners are rebooting their modems and running speed tests at the moment in your area? : ) |

I am seeing the same thing. Very little or no power boost now. And the shaping is not smooth at all for the sustained rate. I'm actually all for zero power boost if the shaping were smooth for the 27/7 rates, as it would let me do proper QoS and not have to deal with powerboost funkiness. But it seems the boost is kinda/sorta there, but misconfigured, or the shaping for the 27/7 is not quite tweaked properly. Perhaps SteveTeow can shed some light? |

Actually, I take that back. I am seeing ~65 Mbps boost now. Previously I was seeing 100+. So that's still there, just not as much. I'm fine with that, although I still wish there was a way to opt out of powerboost entirely. quote: Upstream: No shaper detected. Median received rate: 7242 Kbps.
Downstream: Burst size: 20136-20323 KB; Shaping rate: 28634 Kbps.

I'm seeing the same thing here is Silicon Valley. Speeds have been all over the board since yesterday. Sometimes I get 17/3 sometimes I don't even get close to 12/2. PowerBoost seems to come and go. Estimated Capacity is only a small fraction of what it used to be any time I run ShaperProbe. Here is my latest test. Note I got 17/3 last night: Shaper Detection Module. Connected to server 74.63.50.34. Estimating capacity: Upstream: 1129 Kbps. Downstream: 2248 Kbps. The measurement will take upto 2.5 minutes. Please wait. Checking for traffic shapers: Upstream: No shaper detected. Median received rate: 1120 Kbps. Downstream: No shaper detected. Median received rate: 2202 Kbps. |
