The advantage of a concurrent server is that the server just spawns other servers to handle the client requests.

并发服务的优势在于服务产生其他服务控制用户请求。

youdao

The reason we categorize servers, and not clients, is because a client normally can't tell whether it's talking to an iterative server or a concurrent server.

我们归类服务而不归类客户端的原因是，客户端通常不能区别它是在和一个迭代服务器通信还是在和一个并发服务器通讯。

youdao

For example streaming AMF could cause a large number of concurrent client connections to be open on the server and thus a large number of threads.

例如，流式amf会导致服务器端打开大量并发的客户端连接，这也就意味着会产生多个线程。
