Description Seth Jennings 2022-06-10 14:02:12 UTC

Description of problem:
https://issues.redhat.com/browse/SDN-3132

Version-Release number of selected component (if applicable):
4.11

How reproducible:
always

Steps to Reproduce:
1. Deploy OCP with ovnk SDN
2. Observe memory usage of ovnkube-master pods vs actual usage
3.

Actual results:
Pod uses ~200Mi idle and ~500Mi (~50Mi of that is page cache) under a P90 load as determined by PerfScale. Current request is ~1.5Gi.

Expected results:
Memory requests should align with actual usage.
