Rails performance improvement

I believe the majority of the time I've seen these delays is because of
a resource conflict. Either memory, waiting for a sqlite3 database, or
a resource file lock. It can also come from slow DNS resolving, or back
networking to your MySQL database.

Check those possibilities, and if you're still stuck then hit me up at

And I'll chat with you on some possible tests.
