ISP performance
The research found that cable broadband services delivered significantly faster actual (or download) speeds than comparable services provided via a telephone line:
Virgin Media’s ‘up to’ 10Mbit/s and ‘up to’ 20Mbit/s cable services delivered average download speeds around twice as fast as DSL packages with the same or similar headline speed (see table below).
Virgin Media’s ‘up to’ 50Mbit/s cable service was the fastest service tested, delivering average download speeds of around 36Mbit/s with single thread tests and around 46Mbit/s with multi-thread tests conducted between 4 and 6am. A single thread test involves downloading a single file, while a multi-thread test involves conducting three file downloads simultaneously, which is more typical of the way heavy internet users consume broadband.
