   @tysonnorris For information about Eclipse OpenJ9 and why it might be interesting for a project like OpenWhisk, you can read through the performance statements (and the data that backs them up) at the website https://www.eclipse.org/openj9 (click on the first "Learn more" link you see). For even more detailed info, you can read about OpenJ9 performance at https://www.eclipse.org/openj9/oj9_performance.html .
   
   Quick summary is: start-up can be 30%-40% faster and, depending on how you run, JVM resident footprint can be 40-60% less. If peak throughput isn't your highest priority, then options like -Xtune:virtualized can dramatically accelerate your ramp-up time particularly in memory or CPU constrained environments. And that's with fully open source, independently JCK8-certified builds from AdoptOpenJDK.
   
   I'm not arguing that makes up for the tooling issues that have also been raised here; I'm just responding to your "I know nothing about openj9" comment :) .
   
   Hope that helps! We're happy to answer specific questions here or at our github repo (https://github.com/eclipse/openj9).
