Description
Now that we cleaned up the compilation, I thought it would be interesting to compare the .po / .mo performance.
Script
Gettext Files
I've used the translation catalog of hygeia, which is one of the largest OS ones I know of.

Expo Parse - .po is 11.3 times slower and uses 8.5 times more memory
Gettext Compile - .po is 1.5 times slower and uses 1.5 times more memory

Based on those numbers, we should consider supporting to compile from .mo instead of .po if the user requests it.
EDIT: elixir-gettext/expo#141 will improve it slightly to 1.45 times slower and 1.28 times more memory for the backend compile, but still doesn't come close.
