Additional memory used outside of GC or Web Process has to be reported via reportExtraMemoryAllocated/SlotVisitor::reportExtraMemoryVisited/SlotVisitor::reportExternalMemoryVisited JSC APIs. That should help GC to prioritize heavier objects. A good example is HTMLCanvasElement (CanvasBase). in IDL: [ ReportExtraMemoryCost, ReportExternalMemoryCost, ] In C++: size_t memoryCost() const; size_t externalMemoryCost() const;
