Description Sam Batschelet 2020-03-11 23:16:11 UTC
Description of problem:

the etcd operator is using a fair amount of CPU at idle - ~130m.  It should probably not take that much (since it is merely observing state) - can someone take a look at why it is consuming 2x what OLM takes and 10x what the CVO uses?

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

How reproducible:

Steps to Reproduce:

Actual results:

Expected results: reasonable CPU usage.

Comment 4 Sam Batschelet 2020-05-21 18:07:23 UTC
May 2nd we see CPU about.125- .130m as reported for AWS e2e CI

After https://bugzilla.redhat.com/show_bug.cgi?id=1832901 landed this reduced this to .051 so that is over 90% reduction. We will continue to try and improve but I believe the initial concern has been addressed as .130 was very excessive.

Clarification, the above numbers were during CI run idle is about .029m
