> For all the tests I used MRI Ruby 2.2.2. Unless otherwise noted, I almost exclusively use the most recently released MRI Ruby version for testing. Good to know. I guess I'm suggesting that specifically calling that out in the text will help it stand the test of time. Otherwise the reader needs to cross-reference the date with the MRI release list. And really, this is all I was looking for in the methodology. The post covers what you did in pretty good detail. The GC thing was something I was curious about just because that's ping-ponged quite a bit throughout the 2.x releases. Thanks again!
