Kino: A high-performance Ractor web server for Ruby 4.0
TL;DR
Kino is a high-performance web server for Ruby 4.0+ that utilizes Ractors for parallel processing, significantly improving memory efficiency and speed. It outperforms traditional servers like Puma, achieving 1.5-2x faster response times while using up to 7x less memory.
✦ Why It Matters
Consider switching to Kino for your Ruby applications to enhance performance and reduce memory usage.
Key Takeaways
- Adopt Kino to utilize Ractors for parallel processing in Ruby applications.
- Expect 1.5-2x faster response times compared to Puma on I/O-light tasks.
- Reduce memory usage by up to 7x with Kino's Ractor mode.
- Leverage built-in production features for robust application deployment.
How It Works
Kino operates by using Ractors, which allow multiple Ruby code executions to run in parallel without the memory overhead associated with process forking. Each Ractor has its own lock, enabling efficient CPU utilization across multiple cores.
The server's architecture includes a Rust-based front-end for handling network requests, while Ractors manage the application logic, providing a streamlined and efficient processing model.
