centos7.6操作系统
服务器配置：16核CPU 32G内存 磁盘500G 虚机
问题描述：部署openresty做反向代理，共16个worker进程，线上部署时发现只有8个worker进程CPU占用率比较高，剩下的利用率比较低，CPU整体的利用率大概60%，访问流量的TPS五千左右。预想的结果是各worker进程CPU占用会比较均衡，实际上部署的多台openresty都出现了只有8个进程占用率比较高的情况。请教下这种现象可能的原因是什么？
NGINX部分配置如下：
worker_processes auto;
worker_cpu_affinity auto;
worker_rlimit_nofile 10000000;
events {
use epoll;
accept_mutex off;
worker_connections 65535;
multi_accept on;
}

    whuizzzzzz 非常感谢，开发环境试了下应该是能解决这个问题。想和您再继续探讨下，看了这个指令的用法发现它可能会带来这样一个问题：当工作线程因阻塞操作而停止时，不仅会影响该工作线程已接受的连接，还会影响内核自阻塞以来分配给工作线程的连接请求。因为内核负责根据一定的负载均衡算法将“连接”分配给worker进程，它在分配时貌似不会考虑worker进程是否被阻塞，即使进程被阻塞仍会将新的连接分配给它，也就是说当使用reuseport指令时可能会放大因进程阻塞带来的影响面。不知道您在线上业务环境有没有使用这个指令，有没有遇到类似的问题。
