Hi, 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 # 201 NodePort services $ oc get svc -A | grep -c NodePort 201 sh-4.4# mb -i conf.json -d 120 Time: 120.10s Sent: 278.84MiB, 2.32MiB/s Recv: 2.37GiB, 20.22MiB/s Hits: 1872002, 15587.13/s sh-4.4# mb -i conf.json -d 120 Time: 120.09s Sent: 259.38MiB, 2.16MiB/s Recv: 2.21GiB, 18.81MiB/s Hits: 1741354, 14500.04/s # 1 NodePort service $ oc get svc -A | grep -c NodePort 1 sh-4.4# mb -i conf.json -d 120 Time: 120.04s Sent: 279.15MiB, 2.33MiB/s Recv: 2.37GiB, 20.25MiB/s Hits: 1874053, 15611.81/s sh-4.4# mb -i conf.json -d 120 Time: 120.10s Sent: 286.46MiB, 2.39MiB/s Recv: 2.44GiB, 20.77MiB/s Hits: 1923150, 16013.16/s Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
