statistics page -> 38 seconds to load
global keyword search with a single term -> made two attempts, waited for about 4 minutes both times, and finally got "the page can not be displayed".
on my third attempt, I waited for about one minute, then gave up, closed my browser and opened a new one - for the next 3-4 minutes, all of the pages each took about 40 seconds to load, strongly suggested that the server is still gagging on the aborted search while trying to process new requests at the same time ... it returned to normal after about 3-4 minutes.
I realize this site has 200.000 posts, but ... that is incredibly slow. Do you know what kind of server it's running on? 100 MHz? heh ;)
Let's hope nobody actually uses the search function ... if I had been the webmaster of this site, I think I would simply remove - it's not like anyone is going to wait several minutes for a search result before giving up and aborting, so all the search function does now is choke the CPU ... most pages take at least 20 seconds to load, even if you're not choking the poor server with keyword searches ...
But seriously though, even if our forum only reaches maybe 20.000 posts, I already fear for the impact that searches and page views will have on the response time of other pages on the server :/
I understand what you meant now - MiniBB is great for small and medium size sites, because of it's small footprint, but it should definitely not be used for sites of this magnitude...
