Great article featuring @OpenLibertyIO and an exploration of #Java virtual threads and Open Liberty’s thread pool comparing memory footprint, CPU utilization, throughput and more.

Honored to be speaking today about Cloud-Native Java at the Open Source North conference in beautiful St. Paul. Pls join me in ASC Room C at 1PM.

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

How We Developed the Eclipse OpenJ9 CRIU Support for Fast Java Startup dzone.com/articles/how-we-de… via @DZoneInc Check out this feature that make @OpenLibertyIO an ideal runtime for #CloudNative and #serverless applications.

@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!

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!

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.

Eclipse OpenJ9's Java 21 is finally released!
Key contributors will be giving short presentations on JIT, security, gc and jvm related changes at the community call tomorrow morning. Join for the party 🥳
Hey Eclipse OpenJ9 users! The OpenJ9 project is planning a community meeting Tuesday at 10:30am ET where you'll hear from OpenJ9 developers about the content in our 0.43 (Java 21) release! See the details here: eclipse.org/lists/openj9-dev…

Let's explore the nuances of #JVM within the #cloudnative landscape, and deep-dive into the challenges & innovations in JVM performance for cloud deployments: rb.gy/5i32q
🗣️ Now at #QConSF, Tobi Ajila, Eclipse OpenJ9 JVM Engineer IBM, Optimizing JVMs for Cloud.

What an exciting talk showcasing how innovation in IBM Semeru Runtimes,@OpenLibertyIO and @OpenJ9 has made a real difference for @EclipseStoreIO performance with real workloads. I'm really looking forward to this talk and hope to see everyone there!!
I am looking forward to sharing the stage with @mstoodle and @MarkusKett and talk about new tech in the Java space from the @OpenLibertyIO and @eclipsestore teams. If you are at #ibmtechxchange next week and want to talk Java ping me!

Checkpointing and restoring the JVM makes applications run faster, try it out now with your own apps on @OpenLibertyIO with Eclipse @openj9, with technical challenges described on Foojay.io! foojay.io/today/how-we-devel… #foojaytip

This is incorrect. @openj9 supports AsyncGetCallTrace for two years (github.com/eclipse-openj9/op…) and async-profiler uses this to support the VM since version 2.7 (github.com/async-profiler/as…).

Using @IBMDeveloper. #Semeru. Great support from IBM and the only JVM with a different compiler and memory management (no hotspot, but @openj9). Uses half the memory w/ almost identical throughput.

Finally, IBM Semeru Runtimes Open Edition (containing Eclipse @OpenJ9) can be used with the setup-java GitHub action! Your with: stanza just needs to specify distribution: 'semeru' and you're off to the races!! Thanks to everyone who supported the pull request!
Eclipse OpenJ9 retweeted
Please add your support to this PR to help get @openj9 and Semeru Runtimes added as an option for GitHub actions! It only takes a couple of clicks!
Dear Twitter circle!
Kkindly vote for @openj9 (@IBMDeveloper #Semeru) GitHub support! Just click "thumbs up" on the first post of this issue -- thanks!
