IPC：为每个请求连接或保持套接字打开？ [英] IPC: Connect for each request or keep socket open?

问题描述

我打算使用套接字（本地TCP）在两个进程之间进行通信（在本地运行）。一个进程将充当服务器，但两个进程以异步方式向彼此发送消息。我应该保持套接字连接在进程的生命周期开放，或重新连接每个请求吗？

I am planning to use sockets (local TCP) to communicate between two processes (running locally). One process will act as a server, but both processes send messages to each other asynchronously. Should I keep the socket connection open for the lifetime of the processes, or re-connect for each request?

如果我保留一个本地套接字打开？

Are there any problems that may occur if I keep a local socket open?

推荐答案

保持套接字打开

它是更简单的选项，你不需要承担开启新套接字（从客户端的角度）或接受一个新的客户端（从服务器的角度）的开销。

Its the simpler option and you don't incur in the overhead of opening a new socket (from the client point of view) or accepting a new client (from server point of view).
