Building low latency Java applications with Java 22 and beyond

By dave

This article discusses my opinions around moderate latency and low latency applications built on the JVM using JDK 22 and greater. It is based on many years of trying various approaches. For years the regular way to build exceptionally low latency (or more correctly low GC pause) applications was to avoid memory allocations in the critical parts of the application, and...

Does the native linker change the status-quo for JVM low latency?

By dave

This article discusses if the Java 22 foreign memory API and value classes change my view of the status quo for building applications that communicate with C++ components and the possible latencies in that approach. In the past, with JNI as the C++ go between, there were enough disadvantages that sufficiently down voted this option to the basement. Let's investigate a...
