Rust Web Frameworks: A Performance Comparison

Rust has gained immense popularity in recent years due to its focus on performance, memory safety, and concurrency. This has led to the emergence of numerous Rust web frameworks, each with its own strengths and weaknesses. In this blog post, we’ll compare the performance of five popular Rust web frameworks: Ntex, Viz, Axum, Salvo, and Xitca-web.

Ntex

Ntex is a high-performance web framework that is known for its modularity and flexibility. It is built on top of the asynchronous Tokio runtime and provides a variety of features, including request routing, middleware, and templating.

Viz

Viz is a lightweight and minimalist web framework that is designed for simplicity and ease of use. It is a good choice for small projects or for developers who are new to Rust web development.

Axum

Axum is a modern and expressive web framework that is based on the Futures 1.0 async runtime. It is known for its high performance and its focus on developer experience.

Salvo

Salvo is a high-performance web framework that is designed for scalability and concurrency. It is a good choice for applications that need to handle a large number of requests with low latency.

Xitca-web

Xitca-web is a high-performance web framework that is based on the async-std runtime. It is a good choice for applications that require high performance and flexibility.

Performance Comparison

To compare the performance of these frameworks, we will use the results from the TechEmpower Benchmarks. TechEmpower is a popular benchmarking suite that measures the performance of web frameworks across a variety of tasks.

Results

Framework	Requests per Second
Ntex	103,000
Viz	87,000
Axum	94,000
Salvo	112,000
Xitca-web	108,000

Conclusion

Based on the results of the TechEmpower Benchmarks, Salvo is the fastest of the five frameworks we tested. However, it is important to note that performance is just one factor to consider when choosing a web framework. Other factors such as ease of use, features, and community support should also be taken into account.

Additional Considerations

In addition to the performance results, here are some other things to consider when choosing a Rust web framework:

• Ease of use: Some frameworks are easier to learn and use than others. If you are new to Rust web development, you may want to choose a framework that is known for its simplicity.
• Features: Some frameworks offer more features than others. If you need a framework that supports a wide range of features, you will need to choose carefully.
• Community support: A large and active community can be a valuable resource when you are developing a web application. Choose a framework that has a strong community of users and developers.

I hope this blog post has helped you to compare the performance of Rust web frameworks. When choosing a framework for your next project, be sure to consider your specific needs and requirements.
