As always, whenever i need some good advice, I come here.
Here's a question:
I run a messageboard on my site (www.eldaronline.com/community) and although it's relatively large (8000 users / 160,000 posts / 60k unique visitors per month) it's far from being at the size of the real large boards (such as this one).
A problem of mine is that my board is stupidly slow. I use YaBBSE 1.4.1 (from yabb.info) but I don't think that's the problem, as I've seen other large boards that function at the speed of this one and other vbulletin boards.
we see at any given time 40-50 people on, and max out daily at about 80-100 people. And when that happens, my board comes to a crawl.
