Exploring JITServer on the new Linux on IBM z16 Platform

With the recent 0.32 release of Eclipse OpenJ9, the JITServer technology was officially released and made available for the Linux on IBM z System/LinuxONE platforms. This release also coincides with the recently launched IBM z16 technology. This blog will provide an overview of the JITServer technology and demonstrate some of its key benefits using the…

Save Money with JITServer on the Cloud – an AWS Experiment

With contributions from Marius Pirvu. What is JITServer Technology? JITServer Technology is an Eclipse OpenJ9 JVM technology that decouples the JIT compiler from the JVM and lets the JIT compiler run remotely in its own process. This technique keeps the advantages of JIT compilations while eliminating their negative effects such as CPU and memory spikes,…

A glimpse into performance of JITServer technology

In a previous blog we took a sneak-peek into JITServer technology which relieves the JVM from the negative effects of JIT compilation (interference due to JIT usage of CPU and memory) by offloading it to a remote process. In this article we are going to put this technology to the test, measuring a few key…

Free your JVM from the JIT with JITServer technology

State of the art Java Virtual Machines (JVMs) employ Just-in-Time (JIT) compilers to improve the throughput of Java applications. However, JIT compilers do not come for free: they consume resources, in terms of CPU and memory, and therefore they can interfere with the smooth running of Java applications. Wouldn’t it be nice to keep all…
