Heap objects are not relocated, making it easier for the runtime to support native threads. In addition major GC uses a collector thread that executes asynchronously so application threads can continue to run concurrently even during collections.
In summary:
- All objects on the stack are collected using Cheney on the MTA, and the ones that survive are placed on the heap.
- Heap objects are collected during Major GC using the DLG algorithm.
- Heap collection runs on a separate thread in parallel with application threads.
### Major Garbage Collection Algorithm
Each object is marked with a specific color (white, gray, or black) that determines how it will be handled during a major collection. Major GC transitions through the following states:
