I am consistently getting this in the logs - with values between ~100k to ~1.35m - but the readings near 100k seem to be quite common:

`Your Redis network connection is performing extremely poorly. Last RTT readings were [97069, 103986, 98459, 100762, 381617], ideally these should be < 1000. Ensure Redis is running in the same AZ or datacenter as Sidekiq. If these values are close to 100,000, that means your Sidekiq process may be CPU-saturated; reduce your concurrency and/or see https://github.com/mperham/sidekiq/discussions/5039`

This indicates that perhaps Redis isn’t able to use enough CPU? There seems to be plenty of breathing room for CPU and ram on the server itself though.

also:  
`Sidekiq is consuming too much memory (using: 3570.19M) for 'www.example.com', restarting`

This is using the all in one app.yml with Discourse stable 3.3.2.

From the app.yml:

```plaintext
UNICORN_SIDEKIQS: 9
DISCOURSE_SIDEKIQ_WORKERS: 5

```

I added this configuration to the host also:

> [@MKJ's Opinionated Discourse Deployment Configuration](https://meta.discourse.org/t/mkjs-opinionated-discourse-deployment-configuration/193355/1):

It does seem like Redis is not able to surpass 1024M memory usage.

If anyone has any ideas, I’d appreciate it! :meow_heart:
