Benchmarking programming languages and web frameworks

Shelf (Dart)

Shelf is a modular Dart web server middleware framework inspired by Rack for Ruby and Connect for Node.js. It allows developers to create and compose web servers out of small pieces of middleware and handlers. It is designed to be simple and flexible, allowing for high customizability.

This benchmark tests how fast a framework can perform concurrent HTTP requests, I/O operations, and JSON de/serialization.

MedianP99

Framework	Requests per second Indicates how many requests per second the framework can handle. (higher is better)	Latency Indicates how long it takes to process a request. (lower is better)	Stability Indicates how stable the framework is under load: median / P99 latency (higher is better)	Memory Indicates how much memory (RAM) the framework uses. (lower is better)

About Dart

Paradigm

Object-Oriented, Functional, Imperative

Execution

JIT, AOT

Typing

Static

Null Safety

YES

Memory Management

Garbage Collection

Dart is a client-optimized programming language for fast apps on any platform. It is developed by Google and is optimized for building user interfaces with event-driven programming. Dart supports both just-in-time (JIT) compilation for fast development cycles and ahead-of-time (AOT) compilation for high-performance deployments. Dart is also the programming language behind Flutter, Google's UI toolkit for building natively compiled applications for mobile, web, and desktop from a single codebase.
