I contacted our host today to check on any server issues.* It appears that during those hours there are several hundred simultaneous database connections every minute and there will inevitably be hiccups with that much traffic.* As the site continues to grow we will need to consider upgrades along the way, i.e. adding RAM (memory) to our VPS (virtual private server).* At this point I think we can continue to monitor the server load and optimize the database tables to keep things running smoothly.* There is also a forum software upgrade available (SMF RC 1.3) but I am holding off until the official release later this year.* Let me know if you have questions.
