**因为`PoolWithFunc`这个Pool只绑定一个任务函数也即所有任务都是运行同一个函数所以相较于`Pool`对原生goroutine在执行速度和内存消耗的优势更大上面的结果可以看出执行速度可以达到原生goroutine的300%而内存消耗的优势已经达到了两位数的差距原生goroutine的内存消耗达到了`ants`的35倍且原生goroutine的每次执行的内存分配次数也达到了`ants`45倍1000w的任务量`ants`的初始分配容量是5w因此它完成了所有的任务依旧只使用了5w个goroutine事实上`ants`的Goroutine Pool的容量是可以自定义的也就是说使用者可以根据不同场景对这个参数进行调优直至达到最高性能。** **因为`PoolWithFunc`这个Pool只绑定一个任务函数也即所有任务都是运行同一个函数所以相较于`Pool`对原生goroutine在执行速度和内存消耗的优势更大上面的结果可以看出执行速度可以达到原生goroutine的300%而内存消耗的优势已经达到了两位数的差距原生goroutine的内存消耗达到了`ants`的35倍且原生goroutine的每次执行的内存分配次数也达到了`ants`45倍1000w的任务量`ants`的初始分配容量是5w因此它完成了所有的任务依旧只使用了5w个goroutine事实上`ants`的Goroutine Pool的容量是可以自定义的也就是说使用者可以根据不同场景对这个参数进行调优直至达到最高性能。**
