I've done some tests with the patch and I can verify I haven't seen a significant performance drop when launching a perf test against a cluster with lot of NodePort services:

$ oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.7.0-0.nightly-2021-03-13-033953   True        False         140m    Cluster version is 4.7.0-0.nightly-2021-03-13-033953
