Elsa 3 rc1 beats the record and starts in "just" 6 and 1/2 minutes

There is nothing unusual with the configuration.
I am using PostgreSQL@Docker as a DB, which is shared between Elsa and a client app on my dev machine (MacBook Pro M1).
It is completely unpredictable, as just a couple of minutes ago it took about 5 seconds to start.
Similar slowness happened before, but it never took THAT MUCH LONG, just 10-15 seconds max.
Worked with RC1 for at least a couple of months w/o any updates.
Cannot tell what is going on with it, as it does not say anything. No DB queries in the log during that time, nothing.

Any idea why?
