BIO ServerSocket实现的服务, 服务端一个线程服务一个Client, 即一个Socket, 无多线程时只能服务一个Client, 其他连接均被阻塞, 配合多线程可以实现异步,但是客户端可能突破jvm能创建的线程上限
即使调优Xss, 使用线程池处理,可以限定最高线程数资源,其他Client连接进入队列等待处理?
Q1: Client网络请求连接 ---> jvm Thread, TCP 状态变化? 已接入应用层 ESTABLISHED, TCP连接保持? 内核,JVM线程
Nodejs 单线程就能支持高并发
Q1. 线程模型 与 Java NIO 2.0 对比, 连接
Q2. 异步,线程 栈的处理? 事件?
