去年就已经使用PHP7版本了,那时就说PHP7比老版本快了很多很多,在今年,又分别出了7.1和7.2版本,从 WordPress 4.9.3 开始,该版本修复了 4.9 以来的34个问题。包括外观定制器更改、小工具、可视编辑器和php 7.2兼容性的修复。做了一些对比后,最终决定将博客环境升级到PHP7.2版本。
PHP7.1/7.2对比图:
汇总 | bench.php | bench.php + opcache | micro_bench.php | micro_bench.php + opcache |
---|---|---|---|---|
PHP7.1 | 1.3859 | 0.8133 | 5.6365 | 4.3600 |
PHP7.2 | 1.4514 | 0.7867 | 5.5840 | 3.7234 |
压力测试:
未开启 opcache
# php7.1 Concurrency Level: 10 Time taken for tests: 8.696 seconds Complete requests: 100 Failed requests: 0 Write errors: 0 Total transferred: 5215300 bytes HTML transferred: 5189300 bytes Requests per second: 11.50 [#/sec] (mean) Time per request: 869.637 [ms] (mean) Time per request: 86.964 [ms] (mean, across all concurrent requests) Transfer rate: 585.65 [Kbytes/sec] received
# php7.2 Concurrency Level: 10 Time taken for tests: 8.528 seconds Complete requests: 100 Failed requests: 0 Write errors: 0 Total transferred: 5215500 bytes HTML transferred: 5189300 bytes Requests per second: 11.73 [#/sec] (mean) Time per request: 852.793 [ms] (mean) Time per request: 85.279 [ms] (mean, across all concurrent requests) Transfer rate: 597.24 [Kbytes/sec] received
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。
