The Last Frontier in Java Performance: Remove the Garbage Collector

by Abraham Marín Pérez Follow 8 Followers on  Mar 01, 2017 13

A new JEP draft has been filed to create a no-op garbage collector: a GC that doesn't actually reclaim memory. This is aimed at aiding JVM implementers and researches and, to a lesser extent, ultra-performant applications that generate little to no garbage. If the JEP goes ahead, the new GC would be available together with the existing ones, and would have no effect unless explicitly activated.
