OOC, why isn't this part a ruby default? Isn't it always better to be more memory efficient. (I'm trying to understand what the trade offs are, if any)

EDIT: well, exactly 6 minutes later, I'm done. I followed these instructions: https://elements.heroku.com/buildpacks/gaffneyc/heroku-build...

The app seems to work like usual, I'll just have to wait and see what happens to memory use.

I will reply here in 12 hours with a screen shot showing the results (before/after memory use), whatever they may be.

Also, for reference, here's the metrics for the past 24 hours (LOTS of memory problems): https://imgur.com/a/M8IHd5z
