A month ago, Multibyte support was added to rails, which is a great thing for internationalization. However, it had this nasty habit of loading a Unicode codepoint database on startup, even if the application isn’t using it. I just committed a fix to Rails that should help out with the memory usage. Mephisto doesn’t use the UTF-8 Handler now, so you should see some nice savings in memory.
If you want to try it out, just freeze your edge rails to revision 5476 or higher.
