Description
There are many kinds of containerized applications with different performance objectives. E.g., for short-lived apps, start-up time may be more important. Long-running apps may care more about throughput, response time or memory conservation.

With the many VM options (related to GC, compiler, class loading, etc), it becomes a daunting task to pick the best set of values to satisfy the need of each containerized applications. Hence, we should provide a Tuning Guide, which would include:

1. Recommended VM option setting for various *typical* containerized applications;
2. Steps that a developer can take to determine the best VM option settings for their own containerized applications.

We can probably use some of the very good CDS/AOT tuning instructions from Matthew Gilliard of the JFaaS team: http://mjg123.github.io/2017/10/02/JVM-startup.html http://mjg123.github.io/2017/10/04/AppCDS-and-Clojure.html
