BT and P2P

Hello

I know BT "traffic shape " all P2P traffic but what sort of speeds are people getting on a line speeds of "Up to " 8Mb

Basically it goes something like this... (based entirely on my experience).

Unless the exchange is congested, random wind direction, etc. while your useage is <"80"gig in a month (before getting the warning email) you will get full speed 24x7.

Once you have the warning email then during peak time (5pm til midnight) P2P will be throttled to 1Mbit/s but full speed all other times.

Once you exceed 100gig for the next 30 days you will get full speed P2P between 2am and approx 8-9am, 2Mbit/s P2P from ~8am til 5pm, ~256kbit/s from 5pm til midnight and 2Mbit/s again from midnight til around 2am.

If you've been flagged as a heavy user for 2+ months on the trot, or use massively over 100gig in a month, you will see speeds as low as 33kbit/s for P2P during peak time.

From my experience the warning email is actually triggered by useage of around 50-60gig combined up and down traffic - not 80 as it states - and you will be traffic managed from the point of the email onwards - not from the point you exceed 100gig as it states - although you won't be as agressively managed as you will once you exceed "100"gig... which from my experience is anywhere from 60 to 80gig of actual useage.

If your exchange is congested or (I'm guessing) there are multiple complaints of slow speed on your exchange you will see the same rules applied to P2P as if you are a heavy user even if your within useage limits.

Oh and this is what I'm getting during peak atm..

"Your ISP possibly rate limits your BitTorrent downloads. In our tests a TCP download achieved at least 1653 Kbps while a BitTorrent download achieved at most 59 Kbps"

"Up to 8Mbps" means two things. (It used to only mean the first of the two below ).

First is the connection speed which is mainly dependent on the length and condition of the line between you and the exchange, (indicated by the Attenuation figures), and the condition of your premises' phone wiring.

Second is the throughput achieved as a proportion of that connection speed.

So on a shortish line connecting at over 6Mbps a P2P speed of 100KBps is poor, on a longish line connecting at 1250kbps it may be excellent.

The rest is as Rroff has already posted.

In my experience p2p is throttled to dial up speeds in the evenings. Overnight it goes full speed, office hours is variable.
