EventMachine vs Async: Which is Better for Ruby?

What's the difference between EventMachine and Async in Ruby?

EventMachine is a library for building event-driven applications in Ruby, while Async is a more modern approach that uses fibers for concurrency.

Which one is better for handling multiple connections?

EventMachine is well-suited for handling many simultaneous connections efficiently, but Async can offer simpler code with its fiber-based model.

Are there any performance benchmarks comparing them?

Yes, benchmarks often show EventMachine performing better under heavy loads, but Async can be more efficient for I/O-bound tasks.

What are some use cases for each?

EventMachine is great for real-time applications like chat servers, while Async is ideal for web applications that require simpler concurrency.
