What is the minimum memory footprint for a simple grails application?

Question

We are deploying a simple REST grails (2.3.7) app to heroku. The application is doing little less than "Hello World", yet we exceed the 1x dyno limit of 512MB (usually going between 600-700MB).

What is the expectation of memory usage of such an application?

Also, is there an official minimum requirements concerning memory?

Answer 1

Currently the minimum for a basic application is around or just above the 512mb amount depending on what the app does. We are aware of the problems this creates for Heroku and currently you need double dynos to run Grails applications on Heroku.

We are working to improve Grails support for micro services and a smaller memory footprint in Grails 3.0.
