I’ve been frustrated with the ~30 second rails environment start up time in production, so been tracing it some, and it seems a huge part of it is the load path craziness.

Here’s a log including 3 files – for some reason they’re loaded differently in each case. Why do the top ones check each subdirectory first before the final directory? Any suggestions on optimizations to make to improve this?
