The site is no longer slow as it was this time last year so difficult to answer this really, - given that we do not know what is running on your PC, - 'couple of years ago if you were on the internet it would be only Internet Explorer or the like running but now it could add a few more programs such as firewall software, anti virus, messenger, pop up blockers etc etc. You could also have some spy ware on your system slowing things down, - run somehing like spy bot - free from cnet.com to see if you have anything.

Sorry not much help but these days thre are so many factors that can slow down performance.
