Tuning Cloud-Native Java Applications for Performance: Scaling Up Versus Scaling Out Introduction All application server environments have one thing in common: limited resources. How best to use those resources will determine the efficiency in processing user requests. There are two...
On Wednesday, April 13th, 2022 at 11:00 AM ET, we presented "Tune Java Garbage Collection to improve performance" on IBM Expert TV. Replay: https://ibm.biz/BdPBhT Presentation: https://ibm.biz/BdPdEJ Speakers: Kevin Grigorenko, Gary DeVal In the presentation, we discussed key...
In this blogpost, I will discuss some best practices for optimal throughput for applications using a Microservices architecture. I will focus on two areas: inter-service requests and JSON processing. Inter-service Calls With Microservices, it is likely that you will be making RESTful...
Operational Uniformity and Capacity Gains w/Open Liberty & Spring Boot apps We recently continued the discussion of containerized Liberty workloads on another Expert TV session. @Michael Thompson , @TIM PICKETT and Tom Watson join Dana Price to explore even more options for...
Number of Liberty JVMs affect throughput and memory footprint Introduction There are many factors that can cause performance issues in an application server environment. Changes to application code, an increase in the client load, and other environmental factors can put a strain on...
Java Garbage Collection (GC) fundamentals As discussed in my prior post about how important GC is to Java performance, typical running Java programs create and release Java objects more-or-less continuously. The automated memory management system for dealing with these object...
Have You Enabled WLM in your WebSphere Liberty Server? Do you have a WebSphere Liberty Server running on z/OS? If so, is it WLM enabled? What is WLM you ask? WLM is the Workload Manager, it is a component of z/OS that is used for categorizing, prioritizing, and routing work....
In this blog post I will show how to create a minimized Liberty container image. The idea is based on an article by Tim Pickett: https://developer.ibm.com/articles/modernize-and-optimize-spring-boot-applications/ . Tim’s article focused on Spring Boot applications in JAR files; I will be...
Better Java Cryptography Performance Encryption is a crucial security aspect of any WebSphere Application Server(WAS) environment. Simply configuring the encryption within your application server will undoubtedly impact your throughput performance. In this blog we’ll discuss...
We are living in a container world and I am a container boy. Okay, so maybe a modified version of Madonna's Material Girl does not come to mind right away. However with more and more workloads moving to containers and their orchestration in Kubernetes, Liberty performance needs to be tracked...
