  1. Intermittent issues. I have a client with a couple of intermittently slow WordPress sites (slow TTFB on the server), but it only happens from time to time. I've done extensive debugging work and cannot figure out what causes it.

  2. I haven't learned how to interpret dev tools Performance tab with regards to frontend performance.

Yea I haven't really cracked the nut of the performance tab.

For the random intermittent time to first byte issue you'll want to do some server monitoring. Maybe a cron job is running a heavy task forcing your server to wait or if the page is regenerating cache for some 3rd party request.
