The PR will resolve two issues.
Use the make_shared to replace std::shared_ptr(new XXX), make_shared will combine the reference count and object create(new) to a memory allocation, but the std::shared_ptr(new XXX) will cause two allocations.
Pass the shared_ptr by reference in some cases instead of pass by value. Copy of a shared_ptr is not cheap, which will call the interlock increase and decrease during the function call. Interlock operation will lock the data bus which means all the cores will be paused to wait for it. In my previous project, when we disable the perf counters(which use the interlock operation internal), we almost get 40% latency improvement.
