We are still setting up our forum. I was in there yesterday going through all the "Options" in the admin for the first time. Adjusting things. Prior to that (the forum has been online for a week) it was running pretty fast. In the last 24-48 hours it has slowed down significantly. Struggles to load pages for a second or two. Not sure which setting I modified might be responsible. We have not enabled performance options yet, but that will come after I figure this out. Is there anything that triggers a bell in your mind which might directly affect performance, in the Admin settings? A few things you can ask me to check? Off the top of my head I can't remember all the things I modified. But going back through some of the Options pages. I think I increased "Store drafts for X hours:" to 24 hours (I don't remember the default). I enabled proxy images because without that, our HTTPS/SSL breaks. (disabling this didnt seem to speed it up) Kind of at a loss. It could be anything.
