Nginx 架构 性能优化

Nginx.conf   work_process配置

CPU 亲和绑定 减少进程的切换，减少性能损耗.

worker_processes  16; 
worker_cpu_affinity 0000000000000001 0000000000000010 0000000000000100 0000000000001000 0000000000010000 0000000000100000 
0000000001000000 0000000010000000 0000000100000000 0000001000000000 0000010000000000 0000100000000000 0001000000000000 0010000000000000 0100000000000000 1000000000000000;

worker_processes 配置的核心数，可以通过top查看, 或者物理CPu个数 * 每个CPU的核数

   worker_cpu_affinity 字符串16表示平均分配

查看work process

ps -eo pid,args,psr | grep [n]ginx
