The big caveat here for folks just getting into web performance is "at scale."

scottjehl.com•54 days ago

yep. It's mostly detective work. Then testing and making typically-small, deliberate changes for potentially big impact.

I know you know. Just chiming in for the folks that might miss that bit and start procrastinoptimizing. I'm, of course, not speaking from hard learned experience or anything.

"procrastinoptimizing" - what a fantastic description

$1 for making the change, $999 for knowing where to make it

How do you get your unit, e2e, performance, and acceptance tests and doc updates to fit on the same line as your change?

Just highlighting the hidden work that 1 line change is supported by.
