Keynote Systems, the expert in Internet and mobile cloud monitoring, monitors the top 10 UK social networking sites on a monthly basis and analyses how these sites perform compared to their competitors. By Robert Castley.

Facebook dropped from the top spot in terms of availability in December with YouTube UK coming in first with a 99.99% success rate for the month. Once again however, Facebook was the quickest site of those monitored, with an impressive average download time of 0.65 seconds.

Bebo was by far the slowest site in December with an average response time of 8.12 seconds – more than five seconds slower than the index average. Only five of the nine sites monitored were able to achieve a response time of less than two seconds. It’s a good rule for sites to aim for a load time of less than two seconds in order to ensure that they don’t drive visitors away with unresponsive sites.

All of the sites, except Hi5, scored an availability of above 99.50%, with Hi5 struggling with an average score of 94.27%. YouTube’s results are particularly impressive given the size of the page and the amount of video content that is automatically loaded. By contrast, Facebook’s home page is very light and so it is therefore not as surprising that this page is quick to load and reliable. Site designers of social networking sites that are not achieving such good scores should look at these factors to see if they can identify any problems that are occurring in order to emulate the impressive performance of sites such as Facebook and YouTube.
