PHP7.2、PHP7.1 性能对比

摘要：鸟哥点评相对于主要优化也是在。基于的脚本测试未开启取平均值取平均值开启取平均值取平均值在本次测试中，未开启的情况下，性能比略有提升，开启之后，比有很大的提升。测试结果和配置参数以及服务器配置有关，仅供对比与的性能。

PHP7.2 更新内容
https://github.com/php/php-sr...
从官方给的文档中，我似乎没有看到关于整体性能方面的修改。

鸟哥点评 PHP7.2 相对于 PHP7.1 主要优化也是在 opcache 。

在本次测试中，未开启opcache的情况下，php7.2 性能反而有些下降，开启opcache之后，性能追赶上来，比php7.1略有提升。所以更应该开启opcache了。

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。

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。

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。
