PHP7.2 Update github.com/php/php-src… I don’t seem to see any changes in overall performance from the official documentation.

PHP7.2 is also optimized in Opcache compared to PHP7.1.

In this test, without opcache enabled, THE performance of PHP7.2 decreased somewhat. After opCache was enabled, the performance caught up and improved slightly compared to PHP7.1. All the more reason to enable OpCache.

In this test, when opcache is not enabled, the performance of PHP7.2 is slightly better than that of PHP7.1. After Opcache is enabled, the performance of PHP7.2 is much better than that of PHP7.1.

Considering that other services such as my blog are already running on this server, the number of phP-fPM child processes is only 15, compared under the condition of the same configuration file.

WordPress pressure measurement

Not open 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] ReceivedCopy the code

# 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: 852.793) 85.279 [ms] (mean, across all concurrent requests) Transfer rate: 597.24 [Kbytes/ SEC] ReceivedCopy the code

As you can see, the performance is very poor when opCache is not enabled. With 10 concurrent requests, the response time per request is already very long and there is no need to increase the number of concurrent requests.

After OpCache is enabled

With OpCache enabled, performance is dramatically different than it would have been otherwise. In contrast, PHP7.2 on wordpress pressure test, THE QPS stable at 70+ relative php7.1 increased a lot.

The test results are related to configuration parameters and server configuration and are only used to compare THE performance of PHP7.1 and 7.2.
