配置說明
2核 Intel(R) Xeon(R) CPU E5-2640 0 @ 2.50GHz 內存 4G 系統 Centos 6.2 nginx 1.10.1 mysql 5.5.28 wordpress 4.8.1
考慮到該服務器上已經在運行我的博客等其他服務，所以php-fpm子進程數只配置了15個，在相同配置文件的條件下對比。
# php-fpm 簡單配置，僅供測試
[global]
pid = /data/local/php7{x}/var/run/php-fpm.pid
error_log = /data/log/php7{x}-fpm.log
log_level = notice
[www]
listen = /tmp/php7{x}-cgi.sock
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = static
pm.max_children = 15wordpress 壓測
未開啟 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
可以看到在未開啟opcache的情況下，性能非常糟糕，10個并發的情況下，每個請求的響應時間已經非常長了，沒有必要繼續增加并發數了。
開啟 opcache 之后
匯總 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
在開啟opcache 之后，相對之前未開啟的情況性能簡直天壤之別。相比之下php7.2在wordpress壓測上，QPS 穩定在70+ 相對php7.1 增加不少。
測試結果和配置參數以及服務器配置有關，僅供對比php7.1與7.2的性能。
