The UK has failed to make a list of the top 10 countries for average broadband speed.
Akami's State of the Internet Q4 2013 report said broadband speeds had grown year or year, with most countries in Europe achieving a connection speed of over 4Mbps.
The Netherlands and Switzerland led the EMEA region in high broadband adoption as the only two countries with adoption rates above 40%, reaching 45% and 42% respectively.
Five additional countries saw more than 30% of connections to Akamai at speeds of 10Mbps or above.
Akamai found that the average connection speed in the UK for high speed broadband was 43.5Mbps, ranking it 12th globally, in terms of connectivity speed.
Overall, average connection speed in the UK was measured at 9.4Mbps, a 29% increase year on year, according to Akamai.

However, a USwitch survey reported that 40% of people in the UK experience speeds of under 5Mbps. The slowest speed was measured at just 0.6Mbps.
According to the USwitch research, which is based on almost two million speed tests run by broadband users over a six-month period, only 15% of people in the UK experience superfast broadband of 30Mbps or higher.
This suggests uptake of superfast connections is low, according to USwitch. Figures from Ofcom confirm that superfast broadband is now available to almost three quarters (73%) of the UK, yet only 9% of the population is using it, USwitch noted.
In terms of mobile broadband, the UK is also falling behind the rest of the world. Average page downloads in the UK from a desktop device were 1.7 times faster than when the site was accessed from a mobile device, according to Akamai.
In Italy, pages downloaded 1.1x faster on desktops than mobiles, while in France, downloading a web page from a mobile device was 1.3x slower.
In some countries, such as China, page download time from mobile and desktop were the same, meaning the mobile users were not penalised for accessing the site from a mobile device.
