At my work we have a fork of the discourse-docker repo and host it on an EC2 instance. This Wednesday I pulled in changes from the original repo (starting from commit: update docker gc script · discourse/discourse_docker@4e0c969 · GitHub) and update version we’re running.
However after the update we noticed the server is much slower and user requests timeout during peak hours.
Server CPU usage went up and hits 100% during peak hours after the upgrade:
Also in mixpanel we see the response time for SSO is much longer this week compared to last week:

Looking at the code changes its not clear what the cause is. Can someone point me towards a thread to start investigating?
