What are some tips for improving concurrency performance in Ruby?

To improve concurrency performance in Ruby, consider using threads, fibers, or the concurrent-ruby gem. Also, optimize your code to minimize blocking operations.

Can you explain how the concurrent-ruby gem helps with concurrency?

The concurrent-ruby gem provides abstractions like futures, promises, and thread pools, making it easier to manage concurrent tasks and improve performance.

What are some common pitfalls to avoid when using threads in Ruby?

Common pitfalls include race conditions, deadlocks, and excessive context switching. Always ensure proper synchronization and avoid long-running tasks in threads.

How does Ruby's Global Interpreter Lock (GIL) affect concurrency?

Ruby's GIL allows only one thread to execute at a time, which can limit true parallelism. Using multiple processes or JRuby can help bypass this limitation.
