In the end, I just let it be, and let the system work as a
busy-beaver, with the high interrupt rate. Is this a wise thing to
do?

The tradeoff is always going to be latency vs. throughput.

A sane default should defer enough to catch multiple packets coming in
at something close to line rate, but not so much that latency unduly
suffers.
