Matthias,

1. Regardless to number of running processes they all share the same
DSO so process size is not an issue.

But each java process require a Java and C heap, so if you plan to run
many processes in low-resource environment you should tune JVM options
to achieve better result.

2. You might consider to rewrite you business logic to spawn a new
java thread instead of new process.
