3 GC Techniques to Improve Application Performance

Automated garbage collection (along with the JIT HotSpot Compiler) is one of the most advanced and most valued components of the JVM, but many developers and engineers are far less familiar with Garbage Collection (GC), how it works and how it impacts application performance.

First, what is GC even for? Garbage collection is the memory management process for objects in the heap. As objects are allocated to the heap, they run through a few collection phases – usually rather quickly as the majority of objects in the heap have short lifespans.
