Sandbox specifications

To simulate locally some behaviour of an app which is running in a sandbox does anyone know what settings (maximum heap size/JVM params) I need to fill in?

Hey Pim, A sandbox is small cloud environment, so based on what I remember it had the size of a half appengine, what should be 256MB.

The documentation of Mendix points to this page:, but it isn't available anymore by Mendix. Another page is but it doesn't give you the right specs.
