Hi Yuta,

as far as I know you cannot assign more cores to a JobManager.

Can you tell us a bit more about your environment? How many jobs does
the JobManager has to manage? How much heap memory is assigned to the
JobManager?

Maybe you can use a profiler and find out which component consumes so
much CPU resources?

Regards,
Timo
