Too much Ram and Cpu consumption, possible to optimize?

[daic11]

Sure is amazing fork and only the problem (connected with Ruby) I see the resource comsume efficiency.
Is is possible to optimize RAM and CPU consumption somehow?

I am running Sure on a really small server using docker and it should be optimized in my case as much as possible.

Thank you!

Hi @daic11! I'm Dosu and I’m helping the sure team.

Yes, you can optimize RAM and CPU usage for Sure, especially on a small server running Docker. The main levers are configuration settings for Puma (the web server), Sidekiq (background jobs), and Docker resource limits:

• Lower the number of Puma threads and worker processes by setting the environment variables RAILS_MAX_THREADS (default is 3) and WEB_CONCURRENCY (default is 1). For a small server, try RAILS_MAX_THREADS=2 and WEB_CONCURRENCY=1 to reduce memory and CPU usage. These can be set in your Docker Compose file under the environment section for the web and worker services.
• Sidekiq concurrency is also controlled by RAILS_MAX_THREADS. Reducing this will limit how many background jobs run in parallel, saving resources.
• The database connection pool size is tied to RAILS_MAX_THREADS as well, so lowering it helps reduce memory usage.
• Scheduled jobs (like market data imports and sync cleaners) are defined in config/schedule.yml. You can reduce their frequency or disable non-essential jobs to cut down on background activity.
• By default, Docker Compose does not set resource limits. You can add mem_limit and cpus to your web, worker, db, and redis services to prevent any single container from consuming too many resources.
• Sure was originally designed for larger deployments, so these settings are safe to reduce for single-user or small setups without losing core functionality. Maintainers have noted that idle CPU usage is low, but tuning these settings is the best way to optimize for your environment source.

If you want a step-by-step example or want to see exactly where to set these in your Docker Compose file, let me know!

To reply, just mention @dosu.

Interesting observation, but before we make it into an issue we need specifics on what is considered "too much RAM and CPU consumption" because that is vague and relative to the target deployment.

Take a look at #212 where this is also discussed and maybe merge the two conversations with some specifics. I will say this, the people at PikaPods have been running dozens of installs and claim this is sufficient for their users, is that "too much" as you say?
