UK ISP PlusNet has posted some interesting data that shows the distribution of the broadband speeds received by customers on the provider’s network. It reveals that, on BT's older/existing 20CN (up to 8Mbps) platform, the average performance is around 4520Kbps (4.5Mbps). Some 15% of the ISPs end-users also use the old 512Kbps (500), 1Mbps (1000) or 2Mbps (2000) fixed-rate packages.

It's important to know that the performance chart shown below represents 'throughput speed', which is the maximum speed that data will transfer across the connection. The maximum throughput speed is always slightly lower than the sync speed.


Separately PlusNet noted that it currently has over 800 customers on its trial BT 21CN (up to 24Mbps ADSL2+) platform, which has a higher mean speed of 6533Kbps - HERE.
