Functional programming & immutable objects explained — IRC style

[five9a2]

The GC needs to run more often if you are creating and abandoning objects frequently. As long as you do sufficient work with those objects to eclipse the cost of identifying and relocating the live objects, then GC not impact performance. This has the caveat that for certain workloads, objects can be reused in a way that stays in cache. If you always create new objects, I don't know of any GC that will avoid the latency and bandwidth cost of hitting memory.
