You might have noticed that Java uses more memory than other languages. But why is that? There's a tight relationship between memory and processing, both in how they combine to carry out computation in software and in how RAM and CPUs are sold as a package of hardware. Java manages memory in a way that considers the economics of RAM and CPU together. We need to take that principle into account in our code and in how we configure the VM. To learn more about the topic, come to Ron Presler's talk about the principles of Java memory management at JavaOne.

Come to *JavaOne 2026* in Redwood City (California, USA), March 17th-19th, and *get 100$ off* with code *J12026YTS* : https://www.oracle.com/javaone/

Java's higher memory usage compared to other languages is explained through the lens of memory-CPU economics. Java's VM manages memory by considering RAM and CPU costs together, and understanding this principle is key to writing efficient Java code and configuring the JVM properly. The post teases a JavaOne conference talk by Ron Presler that will challenge whether Java truly uses too much memory or whether other languages are actually inefficient by using too little.
