Java 25 introduces Compact Object Headers (JEP 519), delivering up to 30% CPU savings and reduced memory usage for applications with small objects. This user-friendly feature compresses object headers from 12 bytes to 8, requiring only a JVM flag to activate. Extensively validated by Amazon, it enhances performance, reduces GC pressure, and is ideal for modern cloud deployments.
