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。
