Method Detail

performanceTest

@NonNull
public static long[] performanceTest(int threadCount,
                                               int times,
                                               Function<TestParam,?>... functions)

函数性能测试

Parameters:

threadCount - 并行执行的线程数

times - 每个线程运行次数

functions - 需比较性能的函数集，每个函数可以设置一个返回值，表示函数别名，会打印在控制台中

Returns:

costs 每个函数的总耗时

performanceTest

@NonNull
