socket监听久了cpu太高

[m0_37748860]

服务器端socket服务一共有3个线程
1.监听接收消息
2.接收图片
3.向客户端发送图片
cpu几十分钟就飙到90多。求大佬给个解决方案。

找个真正有水平的开发人员重写你说的这些内容是最简单可靠的解决方案。

[维秀斯丢丢]

解决方案是重写。

重写应该是什么思路？

[xuzuning]

你都不说你是怎么写的，如何能有正确解法？

[以专业开发人员为伍]

什么叫做“一共有3个线程”呢？


异步、事件驱动的程序，当没有消息到来时不会占用任何线程，十几万客户端跟服务器联系可能也不过有十几个、二十几个线程在瞬间工作几十毫秒，然后就结束了。哪有什么阻塞着的线程在那里？

肯定代码有问题，贴代码给你解决！

while 写线程

client_Thread = new Thread(ReceiveData);
client_Thread.Start(connection);

不合适，因为每次收到消息都开启一个线程！切线程里面有嵌套了线程，极其不合理，
像你这杨的业务，需要用异步，不用线程！

[编程有钱人了]

看这个文件 用异步
https://www.cnblogs.com/qc-id-01/p/7520633.html

或者用第三方组件，比如HP-SOCKET ，用起来很简单！

[编程有钱人了]

像传输文件这种工作，如果是业务量大，完全不建议用TCP！除非使用情况比较少，文件小等

异步解决了，tks。
