It's pretty rare these days to be on a version this old, but if you're still running Ruby 3.1 in production: it's worth upgrading to 3.2+ purely to get YJIT.
@nateberkopec looking forward to upgrade to 3.1 from 3.0 😭 Is the memory usage increase by YJIT considerable? Say, 30%?
@junkman 15-25 in my experience
