I'm having the similar problems. Postings with and without attachments can take up to 3 minutes waiting time.
Searching is very very slow and even when you try to open a thread it can take about 20 seconds (sometimes it just hangs)
I use Tab browsing with both Firefox (Default) & IE7, the other 4 forums load very quickly, this one is the first tab and the last to load.
I also hope that the problem can be resolved.This is not a complaint just an observation.
