The *basic* ActiveMQ setup, with no features enabled, is somewhat fast and

When you start enabling features, like advisories, scheduling, etc. it
becomes more complicated.

I disabled scheduling but I seem to remember that with it enabled that
there was a measurable overhead.

We don’t use it so I disabled it and moved on.  I’m sure this is
*partially* what you’re experiencing.

We implemented our own scheduler using timestamped queues.  We have 30
second buckets which we fill up and they are serviced once their interval
is reached.

You could use a similar approach.
