Workerman Development Tips Guide: Methods to Optimize Network Communication Performance

Introduction:
In today's Internet era, high-performance network communication is one of the key requirements for many applications. Workerman, as a powerful network communication framework in the PHP field, can help developers easily build high-performance network applications. This article will introduce some methods to optimize network communication performance to help developers fully utilize the potential of the Workerman framework.

1. Use TCP long connection
   TCP long connection is a reliable connection established at the transport layer. Compared with short connection, it can reduce the overhead of connection establishment and closing and improve the efficiency of data transmission. . In Workerman, long connections are used for communication by default, so no additional configuration is required.

Sample code:

// 创建Worker对象，监听端口为1234
$worker = new Worker('tcp://0.0.0.0:1234');
// 注册回调函数
$worker->onMessage = function($connection, $data){
    // 处理收到的数据
    // ...
    // 发送响应数据
    $connection->send($response);
};
// 启动Worker
Worker::runAll();

2. Using multiple processes
   Multiple processes are a common method to improve server performance. The Workerman framework supports the creation of multiple sub-processes through Worker objects. Each sub-process can handle client requests independently to improve concurrency capabilities.

Sample code:

// 创建Worker对象，监听端口为1234
$worker = new Worker('tcp://0.0.0.0:1234');
// 设置启动的子进程数量
$worker->count = 4;
// 注册回调函数
$worker->onMessage = function($connection, $data){
    // 处理收到的数据
    // ...
    // 发送响应数据
    $connection->send($response);
};
// 启动Worker
Worker::runAll();

3. Using event-driven model
   The Workerman framework is based on the event-driven model, and the event loop mechanism enables the framework to efficiently handle concurrent requests. Developers only need to focus on the specific business logic, and the framework will automatically distribute the request to the corresponding processing function.

Sample code:

// 创建Worker对象，监听端口为1234
$worker = new Worker('tcp://0.0.0.0:1234');
// 注册回调函数
$worker->onConnect = function($connection){
    // 连接建立时的处理逻辑
    // ...
};
$worker->onMessage = function($connection, $data){
    // 处理收到的数据
    // ...
    // 发送响应数据
    $connection->send($response);
};
$worker->onClose = function($connection){
    // 连接关闭时的处理逻辑
    // ...
};
// 启动Worker
Worker::runAll();

4. Data compression transmission
   For large amounts of data in network communication, data compression can be used to reduce the transmission load and improve transmission efficiency. The Workerman framework provides the gzcompress and gzuncompress functions to compress and decompress data.

Sample code:

// 创建Worker对象，监听端口为1234
$worker = new Worker('tcp://0.0.0.0:1234');
// 注册回调函数
$worker->onMessage = function($connection, $data){
    // 压缩数据
    $compressedData = gzcompress($data);
    // 发送压缩后的数据
    $connection->send($compressedData);
};
// 启动Worker
Worker::runAll();

Conclusion:
This article introduces some methods to optimize network communication performance to help developers fully utilize the potential of the Workerman framework. By using TCP long connections, multi-process, event-driven model and data compression transmission methods, the efficiency and performance of network communication can be significantly improved. I hope this article can be helpful to developers who use Workerman to develop.
