For each partition the follower will also fetch data from the leader
replica, even if there is no new data in the leader replicas.
One thing you can try to increase replica.fetch.wait.max.ms (default value
500ms) so that the followers's fetching request frequency to the leader can
be reduced, and see if that has some effect on the traffic.
