这是epoll在休眠啊 这个谈不上占用cpu Windows上用的wepoll项目实现的poll 这个底层用的iocp

[coolMre]

这是epoll在休眠啊 这个谈不上占用cpu Windows上用的wepoll项目实现的poll 这个底层用的iocp

没负载任何视频流的情况下，服务器CPU占用一直在30左右也是正常吗？

不正常。 按道理wepoll不会导致cpu空转。 你可以先关闭wepoll的特性，cmake -DENABLE_WEPOLL=off

[xia-chu]

zlm在Windows上默认开启wepoll 不开启的话 用的select方案

关闭wepoll还是会出现CPU过高的问题。
