Estimating Galaxy container size

Is there a ballpark way to estimate the container size required for a given app? We are testing on a Galaxy Standard container with APM and monitoring but we are looking to determine a “cost per user” which is proving really difficult.

I’ve seen some older posts that suggest about 400 connections per container.

Is load testing the only way to figure this out?

Yup, see meteor-down or just use a ddp client directly

You can always ask questions for us in the support as well at

We could help you to understand it better :wink:

In some cases we are going to get in a call so we can understand our apps and provide size recommendations.
