Era

Era is just a pinch of benchmarking sugar in the form of a gem. It prints the time a block takes to execute but still returns its original return value.

Era is inspired by Clojure's time benchmarking function, which very similarly prints the time it took to exectue but returns the expression's value. Era also gives the option to specify the number of times to run the block but still returns the value from the last run.

Era adds the Era.time method to Kernel so you can just time do instead of Era.time do to benchmark your block.

require 'era'

time do
  sleep 2
  1 + 1
end
#>> Elapsed time: 2000.0369999999998 ms
#=> 2

require 'era'

time(1_000_000) { 1 + 1 }
#>> Elapsed time: 75.89999999999999 ms
#=> 2

require 'era'

time 1000 do
  (99 ** 99) / (88 ** 88)
end
#>> Elapsed time: 3.1510000000000002 ms
