High CPU usage in Galaxy with a meteor/apollo app that uses no subscriptions?

I always thought galaxy/meteor’s high CPU usage was from the use of meteor subscriptions. Are there other common things that can cause high CPU even when using no subscriptions? I figured using apollo would make meteor apps 100X more scalable but I have 7 people on the app and am running at 24% memory (using the lowest/smallest container size). That doesn’t seem much different than a regular meteor app that uses only subscriptions.

I’ll maybe look at APM/kadira but thought I’d post here for any high level suggestions.

Don’t be afraid to just get Kadira up and running. I set this up today in two hours on my home server. https://github.com/lmachens/meteor-apm-server
