Real talk from Dave:
I, Dave Rupert, a person who cares about web performance, a person who reads web performance blogs, a person who spends lots of hours trying to keep up on best practices, a person who co-hosts a weekly podcast about making websites and speak with web performance professionals… somehow goofed and added 33 SECONDS to their page load.
This stuff is hard even when you care a lot. The 33 seconds came from font preloading rather than the one-line wonder of font-display.
I also care about making fast websites, but mine aren’t winning any speed awards because I’ll take practical and maintainable over peak performance any day. (Sorry, world)
