=========================================================
区别:
When to use them
If you need more than two points to communicate, use a Queue()
.
If you need absolute performance, a Pipe()
is much faster because Queue()
is built on top of Pipe()
.
------------
结论:
In summary Pipe()
is about three times faster than a Queue()
.
Queue 的底层是使用Pipe来实现的,或者说Queue是对Pipe的进一步包装,所以性能上有所下降,按照上面的参考资料显示速度降为了Pipe的3分之一,但是Queue支持的功能更加广泛,所以使用Pipe还是Queue要综合考虑性能要求及功能需求。
