Can I trace the load time of a Rails partial?


#1

I have a typical rails app with partials to load nav bars etc. My mini-profiler shows one of the partials taking way more time to render vs the rest. Can I use mini-profiler to dig into the rendering of these to see where the time being taken up?


#2

Have you tried running a flamegraph (click the “more” button)

To do so add the “flamegraph” gem to your Gemfile.

Once you get that done you should be able to dig in quite deep see:
