LOL, I wouldn't complain! I wonder if they are increasing their bandwidth, as I've been noticing that I had plataeued a bit, but now averaging higher. I would peak get 30mb/s bursts on a download, but speed tests typically reported 15 - 17mb/s (even after pulling out my Linksys router.) Past couple of days, even right now during the day, I am getting a cosistant 20mb/s+ on the speed tests. It's either that or one of my neighbors is gone Download Speed: 21732 kbps (2716.5 KB/sec transfer rate) Upload Speed: 718 kbps (89.8 KB/sec transfer rate) -Mike |

maybe it's hit and miss.. I just ran another bunch of tests and my speeds were around 5450 - 7500 down... where as earlier I was peaking at 24Mbps.. hmm.. |

Strange, you would think that a company who has its home offices in Philadelphia would implement this in their home market at least some time in the beginning.
Go figure. |

I live in NW indiana and have noticed the burst for a few days. It is strange because sometimes it seems to climb linearly and then cut me down to 800kb a sec. I have seen peaks as high as 6mBYTES a sec (48Mb!) on some servers!
I would not doubt that some local caching is in the works but who cares, this is freakin cool when it works.
My only reservation....FIX MY UPLOAD PLEASE!!!! |

Re: Nothing in Philly YetHeh. COX in GA (Atlanta is their main office) still on 4mbps premier, 9mbps premium- San Diego ands lots of the US are 6mbps premier, and in VA for at least a half year now it's 5mbps and 15mbps if I remember right.
Their home area means nothing to the company's, money does. |

Re: [News] PowerBoostI wish Cox would do this. Its really a great idea, give people the speed for legal traditional downloads, but cut it back for p2p, bittorrent, and other illegal file sharing which consumes the most bandwidth. |

P2P and BT are not necessarily illegal. Please do not generalize. FTP / HTTP downloads can be just as "illegal". |

PowerBoost under the hoodHow is PowerBoost technically implimented, no white papers, no flow charts? What version of DOCSIS is it? How is it set up under the hood? Is it even DOCSIS? Why do DOCSIS cable modems work with it? How is the 62mbit speed burst in the other thread achived if DOCSIS is limited to 40mbit (qam256)? Does DOCSIS 2 do channel bonding? If there is special QOS, what are all the different QOS levels and purposes used for in Comcast's network? Anyone looked at their modem's config files yet? (I am not by location, and never have been a comcast subscriber). |

I can answer some of your questions: 1)How is PowerBoost technically implemented? Best answered here: » [News] PowerBoost2)What version of DOCSIS is it? Presently Comcast is DOCSIS 1.1 3)How is it set up under the hood? N/A 4)Is it even DOCSIS? It has to be compatible with a DOCSIS network. 5)Why do DOCSIS cable modems work with it? N/A 6)How is the 62mbit speed burst in the other thread achieved if DOCSIS is limited to 40mbit (qam256)? N/A 7)Does DOCSIS 2 do channel bonding? No; DOCSIS 3.0 uses channel bonding. 8)If there is special QOS? N/A 9)What are all the different QOS levels and purposes used for in Comcast's network? N/A 10)Anyone looked at their modem's config files yet? The Config files do not change. Maybe some other people can answer the ones I did not. |

Re: PowerBoost under the hood5)Why do DOCSIS cable modems work with it? Because its DOCSIS compliant 6)How is the 62mbit speed burst in the other thread achieved if DOCSIS is limited to 40mbit (qam256)? Many speedtests are inaccurate with certain levels of bursting. Also ever download a file but wait a minute before you select a place to save it? IE can cache a file while you are picking the save directory. Then when you click ok, it 'catches up' and shows some insane transfer rates. 7)Does DOCSIS 2 do channel bonding? DOCSIS 2.0b can bond up to 2 downstream channels. DOCSIS 3.0 will be able to bond more. Most likely 2 to 16 channels. 8)If there is special QOS? All the QOS is based in the CMTS. The software overlay for the CMTS is provided by CAMIANT but fully customized by Comcast ( » www.camiant.com ) Its using PCMM (PacketCable Multi-Media) Technology » en.wikipedia.org/wiki/Pa ··· ketCable9)What are all the different QOS levels and purposes used for in Comcast's network? 6mbps is supposed to burst till 12mbps. 8mbps package is supposed to burst to 16mbps. While Comcast fine tunes these rates we will see some uneven or crazy burst speeds. |

Anyway,this is what Powerboost does for me.I have 8/384.When I start a download it jumps to about 12MBS for the first 20-30 MB.Thats it.Thats ALL it does. It's nothing but a smokescreen. That said I am a recent DSL convert and would never go back unless it was all that was available.I can get FIOS but so far the Comcast 8/384 does all I need.Of course you can never have to much speed,so come on Comcast. |

Clearly you are looking at it solely from your perspective. For a heavy user, where the first 20-30MB is a very small fraction of the total data they download, boosting is nothing to get excited about. But a much more casual user, who rarely downloads files bigger than that, a real world speed increase can be realized. Comcast would probably wouldn't mind getting rid of the most hard core users anyway... it's the light duty users who pay a premium to get their email and web pages quickly that use little of their network bandwidth are the ones that are most profitable to them. Anything they can do to be more attractive to that group without letting the power users use even more bandwidth is going to look good in their eyes. |

P.S.> the powerboost config file was installed on my cable modem when I power cycled it in South Jersey. |

But a much more casual user, who rarely downloads files bigger than that, a real world speed increase can be realized. Point taken but it seems to me that kind of increase is pointless from a practical standpoint.Maybe it has PR value but your 20meg file is still going to be downloaded faster than you will be able to get ready to do something with it.I mean if you click on something and it downloads in 2 seconds instead of 4 you've doubled your DL speed for that file.But what did you do with the 2 seconds you saved?Nothing but stare at the screen and go"Wow,that was fast!" Like I said-pointless from a practical standpoint.Smoke. |

Yes, it's just an issue with where you draw the line. Obviously a 4MB file (which would equate roughly to a 4sec download on the 8Mbit tier) isn't saving a lot of time. But if a 30MB file really is roughly where that line is drawn, we're talking 15 sec vs. 30 sec... which is certainly noticeable. The mainstream customers aren't going to download files larger than 30MB very often, so you can take your same logic and say "if the rare very large file is only going to be slower on speedbooster vs. a 'flat' speed increase once a month or so, what's the big deal?". When you think about the customers who regularly download files bigger than 30MB, we're probably talking about a MUCH smaller group that uses up a MUCH larger percentage of Comcast's bandwidth. As Comcast has proven before, they aren't interested in those customers. They have shut them off without notice. So you can bet they probably aren't going to lose much sleep over their latest "product" not looking as attractive to that group. |
