https://gist.github.com/oreoshake/0bbc278f0fdfd054ba27a0f5e9ca0a10#file-speed-diff-L13 is what copies the dependency lock files

https://gist.github.com/oreoshake/0bbc278f0fdfd054ba27a0f5e9ca0a10#file-speed-diff-L17 installs the ruby dependency manager

https://gist.github.com/oreoshake/0bbc278f0fdfd054ba27a0f5e9ca0a10#file-speed-diff-L18 installs all ruby dependencies

https://gist.github.com/oreoshake/0bbc278f0fdfd054ba27a0f5e9ca0a10#file-speed-diff-L25 is the only step that can introduce change (other than a dependency change)
