測試命令就是這么一條：

ab -t 10 -c 10 <http://www.darwin.com/>

在不做任何優(yōu)化的情況下，結(jié)果是：

Requests per second:    17.54 [#/sec] (mean)
Requests per second:    19.96 [#/sec] (mean)
Requests per second:    14.12 [#/sec] (mean)

.env 里面設(shè)置 APP_DEBUG=false

Requests per second:    22.02 [#/sec] (mean)

將 PHP 版本從 5.6 升級到 7.1，直接安裝最新版本的 XAMPP：

Requests per second:    30.46 [#/sec] (mean)
Requests per second:    26.36 [#/sec] (mean)
Requests per second:    26.11 [#/sec] (mean)

啟用 Opcache：

Requests per second:    202.04 [#/sec] (mean)
Requests per second:    177.29 [#/sec] (mean)

把 Apache 換成 Nginx：

目前php7.1.4配置以后無法使用到opcache，等以后版本穩(wěn)定以后再更新這個數(shù)據(jù)
