实际上,.NET也存在这个MaxIdleConnectionPerServer配置,但是.NET Core这个PerServer被设置为int.maxvalue,所以我们无需关注,.NET真香。 我的收获 通过本文,我们谈到了golang HttpClient的2个坑位、由坑位导致的现象和排障思路,各位看官,有则改之无则加勉。
发送消息也需要去加锁因为要防止出现panic: concurrent write to websocket connection 导致的问题 假设网络延时,用户新增时候还有消息再发送中,新加入的用户就无法获得锁了,后面其他的相关操作都会被阻塞导致问题。 使用channel 优化: 引入channel 新增客户端集合,包含三个通道 ...

conn, err := l.Accept()iferr !=nil{ fmt.Printf("accept error, err=%s\n", err.Error()) os.Exit(1) }goHandler(conn) } } 高性能网络编程的线程模型 TPC TPC 是 Thread Per Connection 的缩写,指每次有新的连接就新建一个线程去专门处理这个连接请求。
