Workerman Development Skills Guide: Tips for Optimizing TCP/IP Communication Performance

Introduction:
In network programming, TCP/IP communication is a commonly used method. As a high-performance PHP Socket network programming framework, Workerman can easily implement TCP/IP communication. However, to achieve efficient communication performance, developers need to master some techniques. This article will introduce you to some optimization techniques developed by Workerman and provide corresponding code examples.

1. Use long connections
Long connections are a connection maintenance mechanism that can avoid frequent establishment and closing of connections, thereby improving performance. In Workerman, enable long connection mode by setting the Connection::$keepConnection property to true.

Sample code:

require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;
use WorkermanConnectionTcpConnection;

$worker = new Worker('tcp://0.0.0.0:8080');
$worker->onConnect = function(TcpConnection $connection) {
    $connection->keepConnection = true;
};
$worker->onMessage = function(TcpConnection $connection, $data) {
    // 处理业务逻辑
};
Worker::runAll();
Copy after login

2. Using event polling
Workerman uses the event polling mechanism by default to process events, which can effectively improve performance. You can use the Worker::$eventLoopClass attribute to specify the event loop class to use. Commonly used event polling classes include Event, Ev and Libevent, etc.

Sample code:

require_once __DIR__ . '/vendor/autoload.php';
use WorkermanWorker;

// 设置事件轮询类为Event
Worker::$eventLoopClass = 'Workerman\Lib\Event';

$worker = new Worker('tcp://0.0.0.0:8080');
$worker->onMessage = function($connection, $data) {
    // 处理业务逻辑
};
Worker::runAll();
Copy after login

3. Use multi-process mode
Since PHP is a single-threaded language, in order to improve concurrent processing capabilities, you can use multi-process mode. In Workerman, you can start multiple processes by setting the Worker::$count property. The default is the number of CPU cores.

Sample code:

require_once __DIR__ . '/vendor/autoload.php';
use WorkermanWorker;

// 启动4个进程
$worker = new Worker('tcp://0.0.0.0:8080');
$worker->count = 4;
$worker->onMessage = function($connection, $data) {
    // 处理业务逻辑
};
Worker::runAll();
Copy after login

4. Optimize code logic
Good code logic can improve the running efficiency of the program and reduce unnecessary overhead. In Workerman development, the code logic can be optimized through the following points:

  1. Reduce network communication: reduce the amount of data transmission, merge multiple small requests into one large request, and reduce the number of network IOs.
  2. Asynchronous data processing: Asynchronousize potentially time-consuming data processing operations and process them in a non-blocking manner.
  3. Cache optimization: Use cache to reduce the number of database operations and improve data access speed.

5. Enable data compression
Enabling data compression can reduce the amount of data transmitted over the network and improve communication performance. In Workerman, data compression can be achieved by setting the Connection::$onBufferFull callback function.

Sample code:

require_once __DIR__ . '/vendor/autoload.php';
use WorkermanWorker;
use WorkermanConnectionTcpConnection;

$worker = new Worker('tcp://0.0.0.0:8080');
$worker->onConnect = function(TcpConnection $connection) {
    $connection->onBufferFull = function(TcpConnection $connection) {
        $connection->encoding = 'gzip';
    };
};
$worker->onMessage = function(TcpConnection $connection, $data) {
    // 处理业务逻辑
};
Worker::runAll();
Copy after login

6. Avoid blocking operations
Blocking operations will cause the running of the program to be blocked and reduce the overall performance. In Workerman, you should try to avoid using blocking operations, especially in the onMessage callback function.

7. Optimize database access
The database is a frequently involved link in Web applications. Optimizing database access can significantly improve application performance. In Workerman, connection pooling technology can be used to optimize database access.

Sample code:

require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;
use WorkermanMySQLConnection;

$worker = new Worker('tcp://0.0.0.0:8080');
$worker->onWorkerStart = function() {
    global $db;
    $db = new Connection('localhost', '3306', 'username', 'password', 'database');
};
$worker->onMessage = function($connection, $data) {
    global $db;
    $result = $db->select('id, username')->from('users')->where('id=:id')->bindValues(['id' => $data])->query();
};
Worker::runAll();
Copy after login

Conclusion:
Through the introduction of this article, you have learned some optimization techniques developed by Workerman and obtained corresponding code examples. By using these techniques appropriately, you can effectively improve the TCP/IP communication performance of Workerman applications. At the same time, I hope these tips can help you in your work.
