Warning

This benchmark has been misleading for a while. It was originally made to demonstrate how JIT compilers can do all sorts of crazy stuff to your code - especially LuaJIT - and was meant to be a starting point of discussion about what exactly LuaJIT does and how.

As a result, its not indicative of what its performance may be on more realistic data. Differences can be expected because

1. the text will not consist of hard-coded constants

# Since unicorn creates a new pid on restart/reload, it needs a little extra love to 
# manage with runit. Instead of managing unicorn directly, we simply trap signal calls
# to the service and redirect them to unicorn directly.
#
# To make this work properly with RVM, you should create a wrapper for the app's gemset unicorn.
