Fast internet connection but very slow browsing

Question

Hi,
For some time now we have been struggling with very slow browsing speeds. Sometimes the web page will not even load. ADSL speed checks show a good up and down speed and shown below and everything appears to run well if we simply download a file.
Do any of the numbers below indicate any problems?
We have various pc's both hard wired and connected wirelessly and the problems are the same on all. The laptop works fine on my office connection.
Any help greatly appreciated.
