> Garbage collection has an overhead too of course, since there is a major cost to discovering what can be freed, while the cost of doing this with smart pointers is zero. Run-time cost for GC can be minimized, if not completely obviated, by having the collector run on a processor other than those allocated for system use. One such example of this strategy is the JVM Concurrent Mark Sweep[0] GC algorithm. 0 - https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/cms.html https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gc...
