Are you sure the slowness is due to job locks? At Y!, we have seen more
slowness due to DB issues usually masking the delay caused by job locks.

The materialisation of 60 instances of minutely jobs takes almost 11 mins and
during this time, none of the commands of coord actions run because of coord
job lock. The patch for materialisation slowness is committed now. We will see
if locks is still an issue post the materialisation fix
> Coordinator action materialization is too slow due to coarse job level locks
