Should I learn swoole or golang?

Swoole is a PHP asynchronous network communication engine for production environments, allowing PHP developers to write high-performance asynchronous concurrent TCP, UDP, Unix Socket, HTTP, WebSocket services. (Recommended Learning: SWOOLE Video Tutorial )

Swoole can be widely used in the Internet, mobile communications, corporate software, cloud computing, online games, IoT (IoT), car networking , smart home and other fields.

Development efficiency

Go language is essentially a static language, with slightly lower development efficiency, but stronger performance and more suitable for the development of underlying software

Swoole uses PHP language, a dynamic scripting language, with the best development efficiency and is more suitable for application software development

IO model

go language uses a single-threaded eventloop Process IO events, implement multi-threaded coroutine scheduling, and execute user-level code

swoole uses multi-threaded eventloop to process IO events, and multi-process execution of user-level php code

Go handles IO events It is single-threaded and cannot utilize multiple cores. Its throughput is slightly weaker than swoole

In the actual TCP/UDP intensive IO stress test, swoole performed slightly better than go

Go coroutine ( Goroutine) runs on multiple threads. Threads can share stacks and file descriptors. It is more powerful and has advantages in implementing connection pools and concurrency libraries. An additional problem is that there is a data synchronization problem, and users need to consider locking themselves.

Swoole's user code runs in a multi-process environment, without locking issues to consider. But there is no direct access to memory and resources. It is necessary to use the Task process to achieve transfer.

Language performance

Go language is statically compiled, the performance of the language itself greatly exceeds that of PHP, and intensive computing has more advantages

php is dynamically interpreted The language performance is poor and not suitable for intensive calculation programs

Using C extensions to implement intensive calculation and large-scale call codes can solve some PHP performance problems
