PHP performance optimization network communication optimization

PHP website performance optimization involves network communication optimization, including using persistent connections, Pipelining, optimizing HTTP headers, and using HTTP caching to reduce request overhead, increase response speed, and improve throughput. In practical applications, an e-commerce website reduced the average page loading time by 20% through these technologies. Specific effects include: persistent connections reduced the average request time to 50 milliseconds, Pipelining reduced the page loading time by 15%, and HTTP headers Optimization reduces response size by 12%, and HTTP caching reduces server request times by 30%.

PHP performance optimization: network communication optimization

In PHP web applications, network communication is often the main bottleneck that affects performance . By optimizing network communications, application responsiveness and throughput can be significantly improved. This article will explore some commonly used PHP network communication optimization techniques and provide practical cases.

Using persistent connections

Persistent connections allow an open connection to be maintained between the client and the server, thus avoiding the need to re-establish the connection with each request. overhead. PHP extensions such as cURL and HTTP provide built-in support for easily implementing persistent connections:

// 使用 cURL 启用持久化连接
$ch = curl_init();
curl_setopt($ch, CURLOPT_PERSIST_CONNECTIONS, true);
curl_setopt($ch, CURLOPT_MAX_PERSIST_CONNECTIONS, 10);

// 使用 HTTP 启用持久化连接
$http = new Http();
$http->setPersistentConnections(true);

Using pipelining

Pipelining allows the client to wait for a response from the server Send multiple requests to reduce latency. In PHP, HTTP clients such as Guzzle can be used to implement pipelining:

// 使用 Guzzle 启用 pipelining
$client = new Guzzle\Http\Client();
$client->setDefaultOption('pipeline', true);

Optimizing HTTP headers

HTTP headers are metadata information for transmitted data. Excessive header information will increase network communication overhead. HTTP headers can be optimized by:

• Removing unnecessary headers
• Reducing the header size (for example, using shorter names)
• Using Compression to reduce header size

Using HTTP caching

HTTP caching allows clients to cache häufig requested resources, thereby reducing the number of requests to the server. HTTP caching can be implemented in PHP in the following ways:

// 使用 PSR-7 响应对象设置缓存头
use Psr\Http\Message\ResponseInterface;

function addCacheHeaders(ResponseInterface $response): ResponseInterface
{
    $response = $response->withHeader('Cache-Control', 'public, max-age=3600');
    $response = $response->withHeader('Expires', date('D, d M Y H:i:s T', time() + 3600));
    return $response;
}

Practical Case

An e-commerce website reduced the average page load time by 20% by implementing these optimization techniques . Specifically:

• Using persistent connections reduced average request time from 120 milliseconds to 50 milliseconds
• Using pipelining reduced average page load time by 15%
• Optimizing HTTP headers reduces average response size by 12%
• Using HTTP caching reduces the number of server requests by 30%

By following these network communication optimization techniques, PHP applications Can effectively improve performance, user experience and business results.
