GitHub - igorkasyanchuk/time_m: The easiest way to measure execution time of your code - simple gem to measure the execution of your code.

Just a little bit better than doing “puts Time.now - start”

IRB has something similar builtin. Rails allows you to do that with Benchmark.measure:

def process
  Rails.benchmark("=== Processing invoices ===") do
    logger.debug("=== Processing started ===")

    process_invoices

    logger.debug("=== Processing done ===")
  end
end

it will output

Yes, I know. This is what I used too, but it’s just more code to type. Also it’s less noticeable in the logs
