默认情况下可能多个进程跑在一个CPU上或某一核上,导致Nginx进程使用硬件资源不均匀,此次优化是尽可能地分配不同的Nginx进程给不同的CPU处理

配置方法案例:
两颗CPU参数配置
worker_processes 2;
worker_cpu_affinity 0101 1010;
四颗CPU参数配置
worker_processes 4;
worker_cpu_affinity 0001 0010 0100 1000;
八颗CPU参数配置
worker_processes 8;
worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;
八颗CPU参数配置
worker_processes 8;
worker_cpu_affinity 0001 0010 0100 1000 0001 0010 0100 1000;
在主配置文件nginx.conf中配置
