API uses lots of CPU by default and requires a CPU limit on docker-compose/kube

What happened?

To trace this, last time I checked it was because the aspnet runner was creating threads since requests were queuing up. I tried to set a thread count limit, but it did not work, and I simply set a CPU limit on docker compose.

We should look into:

• enforcing a thread limit to fix this
• profile the app to know if this is the cause or simply a symptom
