How do different Rails gems compare in terms of performance?

The performance of Rails gems can vary significantly based on their functionality and how they interact with your application. Are there specific gems you're interested in comparing?

I'm particularly interested in comparing ActiveRecord and Sequel.

ActiveRecord is the default ORM for Rails and is known for its ease of use, while Sequel is often praised for its performance and flexibility. Benchmarks show that Sequel can be faster in certain scenarios, especially with complex queries.

What about caching gems like Dalli and Redis?

Dalli, which is a client for Memcached, is generally faster for simple key-value storage, while Redis offers more advanced data structures and features, which can be beneficial depending on your use case.

Are there any tools to benchmark these gems?

Yes, tools like Benchmark-ips and RubyProf can help you measure the performance of different gems in your application.
