The UK website http://www.vnunet.com/ is truly slow.  Maybe it is slow from my location in the USA, but some of the users on their forums have complained about the slowness of the site way back in 2006. 

There are plenty of external javascript sources which are probably slowing it down. 

Clicking on the “Forum” link at the top of the main navigation, brings the site visitor to the page quickly; however, individual threads in the forums load slowly which could indicate sluggish database performance.

After using the site for a few minutes, all of the sudden, it started to respond very quickly.  If this were my site, I’d worry just a bit.
