...and Eclipse @OpenJ9 of course :)

@MarkusKett @OpenLibertyIO You can have a laugh at my own antics, including my amusing quest to get the demo right, starting at about 26:30 in that video. Oh, and you can learn a bit about @OpenLibertyIO, CRIU, InstantOn, IBM Semeru Runtimes, and (not enough yet?) ultra fast 21.8X faster Java startup !!!!!

JCON2024 keynote with @MarkusKett on EclipseStore: simple, databaseless in-memory data processing. Up to 1000x faster queries, up to 99% cloud db cost savings. With @OpenLibertyIO InstantOn and Semeru Runtimes JDK, production ready EclipseStore cluster nodes start in milliseconds

All feedback welcome!! We love to hear back from our users on stuff that goes well and on stuff we can make better!

Dr. Jawa@lofidewanto

@rmannibucau Yes, C# originated from J++ (Microsoft Java). While Java adopted some ideas from C# which took the idea of Java, all OO programming languages share similar concepts. I'm impressed with OpenJ9. For better performance, I'll consider J9 since it avoids compile-time issues.

@tivrfoa @patterson_home @DZoneInc @OpenLibertyIO @openj9 Some references that might interest you or others using quarkus: blog.openj9.org/?s=Quarkus . Not sure what their support stance is, though.

@jcon_conference @IBMDeveloper @OpenLibertyIO @openj9 @jcon_conference All three workshop sections showcase how Semeru Runtimes and Eclipse @openj9 use significantly (half to two thirds) less memory than e.g. Eclipse Temurin with the same heap size settings. I'd love to hear how the workshop works for you!

Eclipse OpenJ9@openj9·31 May

@RpxDeveloper @mstoodle Getting there albeit slowly: @OpenJ9 interpreter can (has?) run on RISC-V and there's community contribution on the JIT side (see github.com/eclipse-openj9…). The base @EclipseOMR project also has a lot of infra and tests RISC-V (see github.com/eclipse/omr/pu…). Contributions welcome!

Discussion about the state of JAVA on the RISC-V architecture... Speaker is the lead for the Language Runtimes working group at RISE (RISC-V Software Ecosystem). The group focuses on: Java (OpenJDK), Go, Python, Android Runtime, .NET Runtime, Javascript (V8 and SpiderMonkey)

@jcon_conference @IBMDeveloper @OpenLibertyIO @openj9 3rd (last) part of the workshop: see how the Semeru Cloud Compiler offloads @OpenJ9 JIT CPU and memory overheads. easy to deploy and enabled a 67% increase in the number of responses processed in the first minute for a JavaEE7 application running with just 1 CPU core and 200MB!

@jcon_conference @IBMDeveloper @OpenLibertyIO @openj9 Workshop part 2: learn about @OpenLibertyIO and Semeru Runtime InstantOn by adding a single line to a Dockerfile to start a JavaEE ready server in 200-400ms with no Java language restrictions. Not using InstantOn? Your server workloads could be starting 10X-20X slower!

In part 1, learn about @OpenJ9's shared classes cache. See why @OpenLibertyIO uses it by default to save roughly 40% startup time v. Eclipse Temurin. Then learn how you can also easily cut ~50% from Tomcat startup with shared cache: on any platform with no language restrictions.

English

Eclipse OpenJ9@openj9·28 May

A great way to learn about how to use all our completely open source JVM technologies: 1) Shared Classes Cache (Java start in 50% of time), 2) InstantOn (Java start 10X-20X faster on Linux), and our JIT server (Cloud Compiler) that offloads JIT overheads to a remote JIT service!

@IrisShaders @Aleksejpesorin @itzTyrion @inkballpro That's not how we would express it: we just don't prioritize raw speed over memory or other metrics like startup time. We aim for more balanced enhancements targeting cost effective deployments. Sometimes that means prioritizing memory over raw speed, but that isn't "the goal".

English

Iris Shaders@IrisShaders·15 Nis

@Aleksejpesorin @itzTyrion @openj9 @inkballpro OpenJ9 is not designed for speed; in fact, it's designed for the opposite. It prioritizes less memory usage over speed.
