EventMachine vs Celluloid: Which is better for Ruby concurrency?

What are the main differences between EventMachine and Celluloid?

EventMachine is an event-driven I/O framework, while Celluloid is an actor-based concurrent object model. EventMachine is great for handling many connections, while Celluloid simplifies concurrent programming with actors.

Which one should I use for a web application?

It depends on your needs. If your application requires handling many simultaneous connections, EventMachine might be better. If you prefer a simpler model for concurrency, Celluloid could be the way to go.

Can you give me an example of when to use each?

Sure! Use EventMachine for a chat server where you need to manage many users at once. Use Celluloid for a background job processor where tasks can run independently.

Are there any performance benchmarks comparing them?

Yes, there are benchmarks available online. Generally, EventMachine performs better under high load due to its non-blocking nature, while Celluloid can be easier to work with for simpler tasks.
