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。

wordpress 压测
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
# http://hk1.php.net/get/php-7.1.10.tar.gz/from/this/mirror$ ./configure --prefix=/data/local/php71 --with-config-file-path=/data/local/php71/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir=/usr/local/freetype --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-intl --enable-pcntl --with-mcrypt --enable-ftp --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --disable-fileinfo --enable-opcache --with-xsl4登录后复制
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 性能对比的详细内容，更多请关注9543建站博客其它相关文章！
