什么是benchmark与baseline? https://www.zhihu.com/question/22529709
folly/Benchmark.h提供了用于编写和执行基准测试的简单框架。当前,该框架仅针对单线程测试。
简单的使用方式:
#include <folly/Benchmark.h> #include <folly/container/Foreach.h> #include <vector> using namespace std; using namespace folly; BENCHMARK(insertFrontVectorX) { // Let's insert 100 elements at the front of a vector vector<int> v; FOR_EACH_RANGE (i, 0, 100) { v.insert(v.begin(), i); } } BENCHMARK_RELATIVE(insertBackVector_0) { // Let's insert 100 elements at the back of a vector vector<int> v; FOR_EACH_RANGE (i, 0, 100) { v.insert(v.end(), i); } } BENCHMARK_RELATIVE(insertBackVector_1) { // Let's insert 100 elements at the back of a vector vector<int> v; FOR_EACH_RANGE (i, 0, 100) { v.insert(v.end(), i); } } int main() { runBenchmarks(); }
