考虑到该服务器上已经在运行我的博客等其他服务，所以php-fpm子进程数只配置了15个，在相同配置文件的条件下对比。

未开启 opcache

可以看到在未开启opcache的情况下，性能非常糟糕，10个并发的情况下，每个请求的响应时间已经非常长了，没有必要继续增加并发数了。
开启 opcache 之后
汇总7.1 Requests per second (每秒)7.1 Time per request (ms)7.2 Requests per second (每秒)7.2 Time per request (ms)c10 n100 60.63 164.939 70.05 142.762 c20 n200 66.27 301.803 70.74 282.719 c30 n300 66.50 451.121 70.89 423.2 c40 n400 67.95 588.683 70.6 566.608
在开启opcache 之后，相对之前未开启的情况性能简直天壤之别。相比之下php7.2在wordpress压测上，QPS 稳定在70+ 相对php7.1 增加不少。
测试结果和配置参数以及服务器配置有关，仅供对比php7.1与7.2的性能。
以上就是认识PHP7.2、PHP7.1 性能对比的知识。速戳>>知识兔学习精品课！
