How to calculate the execution time of a loop?

Question

ruby

Greetings.
How can I calculate the execution time of each loop using Ruby.
Thanks in advance.

Answer 1

In Stdlib: ruby-doc.org/stdlib-2.0.0/libdoc/benchmark/rdoc/Be...

Answer 2

The easiest way is to create a variable before the loop into which to write the current time, and create a variable after the loop into which to write the time.
We apply the arithmetic operation time2 - time1 and get the output of the loop execution time

Answer 3

begin_time = Time.now
10.times do
  sleep(1)
end
puts Time.now - begin_time
