I feel pretty dumb, because I did this to my 2014 MacBook Pro 15":

Folded like an envelope by a gym treadmill. Incredibly, it still ran.

…which is how I ended up with three computers, on which I ran the tests, below.

Right now, at the start of 2018, it’s been ridiculously hard for me to replace both the mobile and desktop functions of my crushedMBP. (I don’t like the user experience of the new MBP’s. And yeah, maybe I overthink decisions like this.)

On the bright side, around this time, I switched from Vagrant to Docker Compose for my Rails development environments (for each client project, and each personal project), and I discovered that I don’t actually need 16 Gig RAM for Rails and Haskell dev any more! Seriously, Docker is a freakin’ miracle.

What follows is a performance test of development tasks on my three new machines.
