Introduction to high-performance network programming library: fasthttp

With the rapid development of the Internet, network programming has become more and more important. High-performance network programming libraries have become the goals pursued by developers. This article will introduce a high-performance network programming library: fasthttp.

fasthttp is a high-performance, fast, lightweight HTTP implementation library. It uses multiplexing technology and can handle multiple requests at the same time. fasthttp has better performance and less memory consumption than Go's standard HTTP library. It also implements some useful features, such as supporting HTTP/1.1, HTTP/2, WebSocket and other protocols.

1. Fast processing of requests

fasthttp’s processing speed is very fast because it uses multiplexing technology. There is a structure named Server in its source code, which encapsulates all methods and properties of fasthttp. The Do method of the Server structure can handle multiple requests at the same time, which means that the performance during high concurrency is excellent.

2. Low memory consumption

fasthttp also performs very well in terms of memory consumption. It consumes much less memory than similar products. This is because fasthttp is more efficient in memory management and adopts the idea of ​​copy-on-write. When a request arrives, fasthttp will open up a new memory space to process the request. This space shares a base memory with the previously used space. If the space used in the previous processing request is used in the new request, the copy-on-write operation will be performed on this space, thus avoiding repeated memory application and copying.

3. Support HTTP/1.1, HTTP/2 and WebSocket

In addition to improvements in performance and memory consumption, fasthttp also implements some useful features. For example, fasthttp supports HTTP/1.1 and HTTP/2 protocols. The HTTP/2 protocol can significantly improve the performance of HTTP, especially when handling multiple requests. In addition, fasthttp also supports WebSocket, which means we can use fasthttp to build real-time applications.

4. Easy to use

Fasthttp is also very simple to use. For beginners, it provides the easyexample directory, which contains many easy-to-understand example codes. For experienced developers, fasthttp also provides some very advanced features, such as asynchronous processing and routing functions.

Conclusion

fasthttp is a very popular high-performance network programming library. Its fast processing speed, low memory consumption, multi-protocol support and ease of use are the original advantages of fasthttp. Moreover, because it uses multiplexing technology, it can perform well in high concurrency situations. I hope this article will give readers a better understanding of fasthttp, so that they can use it to improve the performance and user experience of their projects.
