README

This is a repo for reproduction of issue reported here: rails/rails#48375

Issue:

Reported server timing data for partials appears to be inaccurate. When nested partials are used, the reported data shows the partials taking more time to render than the request in total. Stopwatch verification confirms timing in chrome & firefox.

Noted in FF, Chrome and Safari.

Viewing reported server timings

  1. open network tab
  2. refresh page
  3. click into the request for the page (probably localhost:3000)
  4. click timings
  5. server timings are at the bottom
  6. look for the key render_partial.action_view
