Workerman Development Skills Revealed: Secrets to Improve Network Application Performance

Introduction:
Nowadays, network applications have become an indispensable part of modern life. With the development of the Internet, the performance and stability requirements of network applications are becoming higher and higher. As a high-performance PHP network application framework, Workerman has powerful expansion and development capabilities, which can help developers improve the performance of network applications. This article will reveal some Workerman development techniques to help developers better use the Workerman framework to build high-performance network applications.

1. Use the process model to improve application performance

Workerman uses a multi-process model, and each connection will be assigned to an independent process for processing. The advantage of this process model is that it can make full use of the performance advantages of multi-core CPUs, and can perform load balancing and improve the concurrency capability of the system. The following is a sample code that uses Workerman to create multiple processes to handle requests:

// 创建worker实例
$worker = new Worker('tcp://0.0.0.0:8080');

// 设置进程数
$worker->count = 4;

// 设置回调函数
$worker->onConnect = function($connection){
    echo "New connection
";
};

$worker->onMessage = function($connection, $data){
    $connection->send("Hello $data
");
};

// 启动worker
Worker::runAll();

In this way, developers can adjust the number of processes according to the hardware conditions of the server, make full use of the server's performance, and improve network applications. processing capabilities.

2. Optimize network communication

1. Use long connections: In network applications, each time a connection is established and disconnected, additional overhead will be incurred. Using long connections can reduce this overhead and improve the performance of network applications. Workerman has long connections enabled by default and can be used directly.
2. Use asynchronous IO: The traditional synchronous IO method will block program execution and affect the concurrency capability of the system. The bottom layer of Workerman uses the libevent extension, which can implement asynchronous IO and improve the efficiency of network communication. When processing network communication, developers can use asynchronous IO, as shown below:

$worker->onMessage = function($connection, $data){
    // 异步发送数据
    $connection->send($data, true);
};

3. Reasonable use of cache

Cache is one of the important means to improve the performance of network applications one. In Workerman, you can improve the response speed and concurrency of network applications by using third-party caching components, such as Redis, Memcached, etc. The following is a sample code that uses Redis to cache data:

// 创建Redis实例
$redis = new Redis();

// 连接Redis服务器
$redis->connect('127.0.0.1', 6379);

$worker->onMessage = function($connection, $data) use ($redis){
    // 从缓存中获取数据
    $result = $redis->get($data);
    
    // 发送数据
    $connection->send($result);
};

4. Optimize code logic

1. Avoid too many network requests: Network requests are time-consuming, too many network requests Requests can result in slower responses. During the development process, the number of network requests should be minimized, which can be achieved by merging requests, caching data, etc. Make sure the code logic is concise and efficient.
2. Use asynchronous methods to handle time-consuming operations: In network applications, some operations may be time-consuming, such as file reading and writing, database queries, etc. To avoid blocking the event loop, these time-consuming operations can be handled asynchronously. The Workerman framework provides an API for asynchronous operations, which can easily implement asynchronous processing.

Conclusion:
As a high-performance PHP network application framework, Workerman provides a wealth of development skills to help developers build high-performance and stable network applications. By rationally using the process model, optimizing network communication, rationally using cache, and optimizing code logic, developers can make full use of the features of the Workerman framework to improve the performance of network applications.
