theymos, was this because of new changes again? We need to be more pro-active about forum stability and software if we want to match forum growth, and the growth of Bitcoin as a whole.
No. Traffic is much higher, but I don't know exactly why it gets so slow. Memory usage seems fine now. Things improve after I restart mysql, php-fpm, etc., but then the site gradually slows down over time.
As I said, I'm making arrangements to move to a better server. This isn't as easy as it sounds because I don't (and won't) control any of the forum's critical assets other than the BTC. So I need to get someone trustworthy to buy the server (this part seems OK, but not done yet), and I need to get Sirius to update the DNS (I haven't heard from him yet).
