PHP-FPM Performance Optimization: Methods to Improve the Concurrency Processing Capability of the Website

Overview:
In today’s Internet era, the number of concurrent visits to the website is increasing. , in order to meet the high concurrent traffic, it has become very important to improve the concurrent processing capability of the website. PHP-FPM (PHP-FastCGI Process Manager), as a high-performance PHP solution, can effectively improve the concurrent processing capabilities of the website. This article will introduce some PHP-FPM performance optimization methods and give specific code examples.

1. Enable PHP-FPM process balancing

By default, PHP-FPM process balancing is disabled, which means that each request will start a new PHP -FPM process to handle. In order to improve the performance of PHP-FPM, you can enable process balancing and configure an appropriate process pool size. The following is an example php-fpm.conf configuration file:

[www]
pm = dynamic
pm.max_children = 100
pm.start_servers = 20
pm.min_spare_servers = 10
pm.max_spare_servers = 30

In the above configuration, pm.max_children represents the maximum number of processes in the process pool, pm.start_serversRepresents the number of processes started at startup, pm.min_spare_servers and pm.max_spare_servers represent the minimum and maximum number of idle processes respectively. According to the actual situation, these parameters can be adjusted according to the performance and load of the server.

2. Using PHP Cache

PHP caching can significantly improve the performance of the website. PHP caching allows the PHP script to cache the results after it is executed once, and directly return the cached results on the next request without the need to execute the PHP script again. This can save a lot of CPU and memory resources. The following is a sample code using the OPcache extension:

opcache.enable=1
opcache.memory_consumption=128
opcache.max_accelerated_files=10000
opcache.validate_timestamps=0

In the above configuration, opcache.enable enables the OPcache extension, opcache.memory_consumption specifies the memory used by OPcache Memory size, opcache.max_accelerated_files specifies the number of script files that can be cached, opcache.validate_timestamps controls whether to check the timestamp of the script file to determine whether to update the cache.

3. Use asynchronous IO

PHP-FPM processes requests synchronously by default, that is, each request will be blocked and wait for the processing to complete before processing the next request. Using asynchronous IO can put it in the background when processing requests, thereby improving the concurrent processing capabilities of the website. The following is a sample code that uses the Swoole extension to implement asynchronous IO:

$server = new SwooleHttpServer("127.0.0.1", 9501, SWOOLE_BASE);
$server->on("Request", function ($request, $response) {
    $response->header("Content-Type", "text/plain");
    $response->end("Hello World
");
});
$server->start();

The above code uses the Swoole extension to create a server based on the HTTP protocol and uses asynchronous IO to handle requests. This can greatly improve the performance of PHP-FPM.

Conclusion:
By enabling PHP-FPM process balancing, using PHP cache, and using asynchronous IO, the concurrent processing capabilities of the website can be significantly improved. It is necessary to select the appropriate method and configuration parameters based on the actual situation, and conduct reasonable testing and optimization. As a high-performance PHP solution, PHP-FPM can help websites cope with large traffic visits and improve user experience.
