【C++项目】高并发内存池项目第七讲多线程并发执行情况下的性能分析以及复杂问题的调试技巧

项目源代码：高并发内存池

1.调试代码及分析

#include"ConcurrentAlloc.h"
#include"ObjectPool.h"
#include"Common.h"
void BenchmarkMalloc(size_t ntimes, size_t nworks, size_t rounds)
{
   
   
	std::vector<std::thread> vthread(nworks);
	std::atomic<size_t> malloc_costtime(0);
	std::atomic<size_t> free_costtime(0);
	for (size_t k = 0; k < nworks; ++k)
	{
   
   
		vthread[k] = std::thread([&, k]() {
   
   
			std::vector<void*> v;
			v.reserve(ntimes);
			for (size_t j = 0; j < rounds; ++j)
			{
   
   
				size_t begin1 = clock();
				for (size_t i = 0; i < ntimes; i++)
				{
   
   
					//v.push_back(malloc(16));
					v.push_back(malloc((16 + i) % 8192 + 1));
				}
				size_t end1 = clock()
