Forum on a go-slow this lunchtime. This from the bottom of the forum main page:  "Page created in 30.074 seconds with 23 queries."

Ouch, that is a long time.  Seems to be fine at the moment for me.

It does seem to vary according to what one is looking at.

I find that it can take several seconds (although I haven't seen anywhere near 30s) to refresh the Recent Posts page but gives an almost immediate response if refreshing a page within a thread - which is, I think, not surprising since in the former case the forum software is having to do a lot more work to find, assemble and display what is to all intents and purposes a search result.
