 If your program will generate a massive number of goroutines and you don't want them to consume a vast amount of memory, with ants, all you need to do is to import ants package and submit all your tasks to the default limited pool created when ants was imported:

 All the tasks submitted to ants pool will not be guaranteed to be processed in order, because those tasks distribute among a series of concurrent workers, thus those tasks are processed concurrently.

  In that benchmark-picture, the first and second benchmarks performed test with 100w tasks and the rest of benchmarks performed test with 1000w tasks, both unlimited goroutines and ants pool, and the capacity of this ants goroutine-pool was limited to 5w.

 写 go 并发程序的时候如果程序会启动大量的 goroutine ，势必会消耗大量的系统资源（内存，CPU），通过使用 `ants`，可以实例化一个协程池，复用 goroutine ，节省资源，提升性能：
