Compare workerman and swoole to see which one is faster and more reliable!

Workerman, together with Swoole, is known as a high-performance web framework for PHP. However, there is an argument that Workerman is less efficient than Swoole. In this article, we will compare these two frameworks to see which one is faster and more reliable.

First, let’s understand the basic knowledge of these two frameworks. Workerman is a PHP asynchronous event-driven high-performance TCP/UDP server that can easily handle thousands of concurrent connections. Swoole is also a high-performance PHP network framework and an extension of PHP. Swoole has more functions than Workerman, including asynchronous MySQL, asynchronous Redis, coroutines, etc. But in this article we only focus on performance comparisons between frameworks.

In terms of performance testing, we use the AB (Apache Benchmark) tool for stress testing. The specific configuration of the test environment is as follows:

• Operating system: Ubuntu 18.04 LTS
• PHP version: 7.4
• Memory: 8GB
• CPU: Intel( R) Xeon(R) Gold 6148 CPU @ 2.40GHz (28 cores)

We first created a simple web server in two frameworks to test the performance of the server.

Test command line:

// Workerman
./wrk -c 200 -d 30s "http://127.0.0.1:2345/"

// Swoole
./wrk -c 200 -d 30s "http://127.0.0.1:2345/"

The results are as follows:

After seeing the data, Swoole's processing rate under concurrent access is slightly higher than Workerman, but the gap between the two is not big. Overall, both perform very well. Of course, this is just a simple performance test and may not accurately represent the respective performance in actual applications.

However, Workerman has an important feature, that is, it can run in the PHP process. This means that we can run multiple applications simultaneously in the same process, which is not easy to achieve with Swoole. If the application needs to run multiple services simultaneously, Workerman may be a better choice.

In addition, Workerman supports PHP extensions and Composer libraries, which makes it easier to integrate third-party services and make flexible combinations. Swoole needs to be configured at compile time, which is relatively more difficult.

Overall, although Swoole is slightly better than Workerman in overall performance, Workerman, as a pure PHP library, also has its own advantages. According to different application scenarios and needs, developers can choose a network framework that is more suitable for them.
