python - 使用goroutine+channel和java多线程+queue队列的方式开发各有什么优缺点？

Question

我感觉很多项目使用java或者c的多线程库+线程安全的queue数据结构基本上可以实现goroutine+channel开发能达到的需求，所以请问一下为什么说golang更适合并发服务端的开发呢？使用goroutine+channel和java多线程+queue队列的方式开发各有什么优缺点？

Goroutine has less overhead than thread and is simpler

Answer 2

Threads need to grab locks, which will waste CPU performance and turn parallelism into serialization. Gorouten uses notifications to send data to a separate thread to make a copy, and then other threads do not need to compete for locks to truly execute in parallel
