The core idea is that removing object identity (one bit per object) across millions of objects leads to dramatically lower memory consumption and better execution efficiency. This is framed as a potential game changer for the JVM platform, improving startup times, developer experience, and making the JVM cheaper to run — provided Java compatibility is maintained. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are JVM value types and how do they improve memory efficiency? JVM value types remove object identity — effectively one bit per object — which allows the runtime to compare objects by value rather than reference. Because there are so many objects in a typical JVM application, eliminating that identity bit enables inlining, alignment shortcuts, and dramatically lower memory consumption, making the JVM cheaper to run and faster to execute. _Java developers tracking JVM performance improvements follow developments like these on daily.dev._ ## Similar posts on daily.dev - [Java’s biggest language change in a decade is finally landing.
