Re: How to get full 12/2 speed.....?? @Merlin: Where?
Even EDGE had backhaul problems in 2007 when the iPhone hit. It's fundamentally the same issue, even if the timescale is different.
I don't really care what AT&T's backbone looks like, as long as it can handle the last-mile. And they have poor last-mile. AT&T should be looking towards 100% GPON coverage, and they aren't even looking at 1% GPON coverage.
Mackey, I'm pretty sure T does, they are a larger backbone/ global carrier than just about anyone else. Comcast and Verizon pale in comparison.
You do need a decent sized file to notice PB. However, it helps a LOT with starting streaming, and it makes it FEEL faster. It's worth something to me. |

Bet the cable co loves people like you that can "FEEL" that placebo effect!
Ahh yes, now I see why in my experience PowerBoost has done ABSOLUTELY NOTHING to make streaming/web page browsing ANY faster than the equivalent connection without PowerBoost:
quote:
Powerboost is per user connection, not per TCP flow. All
simultaneous TCP flows from a subscriber’s cable modem
will share the same Powerboost token buckets. This includes
multiple users in the subscriber's household.

SOO basically only the first few MB of a website are "boosted" PERIOD. Not the first few MB of every single image/text/whatever that is loaded per page. Also PowerBoost doesn't work EVERY time you load a page. THEN there's the fact that when downloads are negotiated, when the "boost" kicks in the server (if it has the capacity) will send the data at that rate, then, when the PowerBoost goes away, then you've got a bottleneck, so the server is still sending the data at the "boosted" rate, thus packets are dropped and the server has to resend/renegotiate the connection.
In other words, LITTLE to NO advantage (other than tiny files, artificially inflating speed tests and/or making it harder to diagnose QoS/connection issues!) Just look at the data in the PDF! So much for "benefits!"
Not to mention, that latency and QoS matters MUCH MORE for most Internet applications than raw speed! |

| I KNOW that I am getting it. I can SEE that my computer is using about 2.5MB/s, and that loading times are lower. Connections without it feel slow now.
It's the first 20MB, and oftentimes, if you have a lot of stuff downloading, or a batch process like file backup, you will get Powerboost over and over and over, creating all sorts of spikes in bandwidth that speeds up everything a LOT.
That's all nice in theory, but IRL, you're just wrong. |

| Yeah OK! lol enjoy your placebo! My U-verse connection gets 2.5MB/s without PowerBoost... Oh and did I mention no cap? lol |

EARTH | Well, we got upgraded to 16mbps yesterday, so I'll take that over a crappy 1.5mbps AT&T DSL line any day! |
