Speed Lab

## What it does Works through a ranked list of around fifty front-end performance techniques, applies each one, measures whether it actually helped, and keeps only the changes that did. It can grind through the list itself or hand the work to a cloud agent while you watch. It runs when you ask it to, rather than on a timer. ## Before you install Open the share link and read the instructions it carries before you add it. Jacob shared this one publicly, and adding it copies the setup into your own account rather than giving you access to theirs.
