不知道你做过性能测试没有，但根据epoll的特性，性能还不如阻塞读写

Hi Developer - Sometime it may happen that during writing it may return EAGAIN .. means send buffer may be full try again later.

Can you please handle that case. I mean storing the message in the local user buffer and retry to write again when write events happen.

Thanks

ecbuf_capacity_extend()函数的realloc失败了，请教一下楼主。错误输出如下： [code=csharp] buff capacity extend error
expand capacity fail, failtimes = 1
buff capacity extend error
expand capacity fail, failtimes = 2
