Fundamentals of garbage collection (2023)

Learn how the garbage collector works and how it can be configured for optimum performance.

An application's roots include static fields, local variables on a thread's stack, CPU registers, GC handles, and the finalize queue. The intrusiveness (frequency and duration) of garbage collections is the result of the volume of allocations and the amount of survived memory on the managed heap. To optimize the performance of the garbage collector, the managed heap is divided into three generations, 0, 1, and 2, so it can handle long-lived and short-lived objects separately.
