The current Nasal garbage collector (GC) is known to influence the frame rate in FlightGear and occasionally cause stutter under certain circumstances. This is largely attributed to it being a fairly simple sequential mark/sweep collector, which needs to stop all operations, mark all reachable objects and free unreachable objects in an exclusive, single-threaded, fashion. | The current Nasal garbage collector (GC) is known to influence the frame rate in FlightGear and occasionally cause stutter under certain circumstances.

In other words, the time spent in the GC is proportial to the number of active objects, even for objects which may not be running - just loaded. | In other words, the time spent in the GC is proportial to the number of active objects, even for objects which may not be running - just loaded. | ||
