Epitiro have released the latest performance figures from their ISP-I performance testing. The tests check 16 different performance metrics from 11 of the largest ADSL broadband providers in the UK. The data released covers Q3 & Q4 (combined) for 2007. Readers should be aware that as Epitiro only test the 11 largest providers, this does not represent the best of the industry.
|Rank||Q3 & Q4 2007||Q2 2007||Q1 2007||Q4 2006||Q3 2006|
The other providers who were tested, but didn't make the top 5 include TalkTalk, AOL, Virgin, Tiscali, Tesco and Demon. As always, BT retain their top position, as they have done since Q2 2006. Plusnet have climbed 3 places to be ranked 2nd overall, and O2/Be has joined the ranks in 3rd place. Demon, a regular name within the top 5, failed to appear for Q3 & Q4.
A further break down of some of the individual performance metrics that Epitiro undertake can be seen below.
|HTTP Download||Non Cached HTTP Download||Webspace FTP Download||Webspace FTP Upload|
|Q3 & Q4 Industry Average||62.08||39.75||233.91||38.54|
|Q3 & Q4 Top 5||
|Ping Time (s)||DNS Lookup Time (ms)||Packet Loss (% of total packets)|
|Q3 & Q4 Industry Average||0.09||65.21||0.1|
|Q3 & Q4 Top 5||
One possible reason that O2/Be have performed so well is their use of ADSL2+ technology which allows them to outperform everyone else in the HTTP download tests as the line can connect at a higher speed. The break down is interesting as it does give some insight to where different providers perform better or worse.
Surprisingly, the industry average for the FTP Webspace download, which should be hosted directly on the ISP's network, is much higher than that of the HTTP downloads. This helps to show that often the speed up to the service provider can be fine, but beyond that outside of their network, a lot more contention and traffic shaping comes in to play.
