For those interested in very technical things, during the move to CentOS, some things were changed for various reasons, mostly performance.
1. We now talk to the PHP FastCGI workers over Unix sockets. This should provide better performance, as no TCP connections are being created (which if you think about it, can be very slow comparitively), so loopback won't be always busy. In theory, Unix sockets are much cheaper than TCP because nothing is being checksummed, and there's no acknowledgement packets.
2. We heavily increased the number of Nginx and PHP FastCGI workers. This means more requests can be answered simultaneously, and multiple people can be posting at the exact same time (well, more PHP can be doing work that happens before and after database work, such as reading in uploads, or building pages, etc. because the tables will be locked when writing because it's MyISAM)
3. We moved Lunachan into a directory that won't be changed by any updates. Lunachan also no longer resides in Zeke's site's directory (eggbertx.theoks.net/chan/ will no longer work). If you have a HUGE need for that to function again, I can whip up some redirection magic that will redirect your request properly. Remember though that we became Lunachan many moons (months) ago, and the preferred method for accessing Lunachan has been lunachan.net for just as long.
