What is the Ruby Benchmark module and how do I use it?

The Ruby Benchmark module is used to measure and report the time taken to execute Ruby code. You can use it to compare the performance of different code snippets.

Can you show me a simple example of how to use it?

Sure! Here's a basic example:

require 'benchmark'

time = Benchmark.measure do
  # Your code here
end

puts time.real

What kind of code should I benchmark?

You can benchmark any code that you suspect might be slow or that you want to optimize, such as loops, database queries, or complex calculations.

Are there any best practices for using the Benchmark module?

Yes! Make sure to benchmark in a controlled environment, avoid including I/O operations, and run benchmarks multiple times to get accurate results.
