Ref: #2789

Still an issue in v1.6.6.

[hackdna]

RDS CPU utilization is also high.

scc-prod running v1.6.6 (~10%):

vs rds-refinery-of963ie running an earlier version (~1.75%):

[hackdna]

The baseline CPU utilization has now climbed to over 50% on the production SCC instance.

CPU utilization is hovering around 5% as of today. Can we close this?

OK but before closing it would be great to set up some CloudWatch alerts to keep an eye on this.

Let’s close and create a new issue to set up a CloudWatch monitor.

I'll set this up in Terraform for deployments going forward and for the current production instance as well
