How can I profile the performance of my Ruby application?

You can use tools like RubyProf, StackProf, or the built-in Benchmark module to profile your Ruby application.

What are the differences between RubyProf and StackProf?

RubyProf provides detailed reports and supports various output formats, while StackProf is faster and uses less memory.

Can you show me a simple example of using the Benchmark module?

Sure! Here's a basic example:

require 'benchmark'

time = Benchmark.measure do
  # Your code here
end

puts time.real

Are there any best practices for performance profiling in Ruby?

Yes, focus on profiling in a production-like environment, avoid profiling in tests, and analyze hotspots to optimize.
