How many memory (RAM) does the process engine need?

I need to decide between two servers, one with 2 GB memory and the other with 4 GB. My question is do you think that 2 GB would be enough for a Debian 8 headless server running a Tomcat server with shared process engine taking care of only 2 simple processes and communicating with an external database?

Maybe someone can tell me the expected memory usage for this kind of setup using the linux command “free -m” or something similar.

Hi @Mathias_S,

default setting in Tomcat distribution are -Xmx512m -XX:MaxPermSize=256m -XX:PermSize=256m it is really hard to say if that will be enough in your specific case, I guess you will have to find out yourself as it highly depends on what kind of processes you run on it. But in general those settings allow to run a dozen of processes without any problem.

Hope that helps,
