stevenacoffman/java9-bench repository overview

⁠Smaller Java 9 apps in Docker

This project showcases what is in my opinion the coolest features in JDK 9:

• ability to create custom runtime for your application
• native support for Alpine Linux

This translates to less disk space and faster startup times than the full JVM. Whether or not it improves memory usage or speed after initial startup is an open question in my mind.

⁠TL; DR version

REPOSITORY=stevenacoffman/java9-bench
