📝 Log Timings with Rails.logger.benchmark

Rails extends the logger with benchmark to log execution time directly in your logs. Wrap any block in controllers, models, or jobs to automatically output timing info without extra setup.

class ProductsController < ApplicationController
  def index
    Rails.logger.benchmark("Loading products") do
      @products = Product.all.to_a
    end
    render json: @products
  end
end
