What are some effective Ruby profiler tools?

There are several great Ruby profiler tools, including RubyProf, StackProf, and the built-in Benchmark module. RubyProf provides detailed reports on method calls, while StackProf is known for its low overhead.

Can you explain how to use RubyProf?

Sure! To use RubyProf, you need to require the gem in your Ruby script, then wrap the code you want to profile with RubyProf.profile. After running your script, you can generate a report to analyze the performance.

What are the differences between RubyProf and StackProf?

RubyProf offers detailed method-level profiling, while StackProf is designed for low overhead and can handle larger applications more efficiently. StackProf is often preferred for production environments.

Are there any built-in tools in Ruby for profiling?

Yes, Ruby has a built-in Benchmark module that allows you to measure and compare the execution time of different code blocks. It's not as detailed as RubyProf, but it's useful for quick performance checks.
