Yeah! Full credit goes to Nathan Woodrow here, this panel just exposes
a profiling tool he added a while back.

This is EXACTLY the kind of issue this was added for! I also see
occasional 5 minute+ startup times on Windows (bare metal installs)
and would like to get this resolved for 3.14. (It's a bad experience
for users, and when things are working correctly QGIS should startup
in a couple of seconds at most. Our (usual) speedy startup is
something which differentiates us from a certain other desktop GIS
application ;)

It will, it's just that the Windows nightly builds are too old to have
it. It looks identical to your screenshot.

On that note, 12 seconds is a long time for the plugin load I see in
your screenshot. Can you expand that out and see if it narrows down
the culprit?
