It has been mentioned in the forums that the site speed is sometimes rather slow.
Firstly for me it appears that the load time is slow however, after that things speed up. I believe this is similar to other community server based sites so there may be little that can be done.
On the general speed side of things, the site will be moved to quicker hardware and a faster Internet connection in the next week or so, so if you can bear with me until then that would be great.
If things are very slow at specific times please let me know and I will investigate further.
