Cmonkey and the rest of the administrative gang have been doing all they can to help the move from the old boards to Simple Machines Forums. The database error some people were receiving should not be corrected, and a new spongebob theme for the forum is in the works.
SMF has seemed very speedy to me from the beginning, but when I noticed it supported APC natively I decided to implement it. APC stands for Alternative PHP Cache and it caches the intermediate PHP code. This means that, when you request a page, instead of going through these steps (human-readable code > intermediate code > running script) it just does the last two (intermediate code > running script) until the source file (human-readable code) is changed.
This has sped up SMF a whole lot, changing rendering time from .1** seconds to .07* seconds. This should cause no problems, but there is always a chance it will. If anyone is experiencing any odd problem which have cropped up recently (today or after), PM me with the error info (if available) and I'll look into to. Also, United SpongeBob may have been down for a few seconds here and there between 4:00PM and 4:10PM EST while APC was compiled and installed as a PHP extension.
Enjoy the new boards!
