_{Official ZPE/YASS documentation}Utilities : benchmark

benchmark (map|list processes[, number warmups[, number runs]]) ⇒ map|list

Benchmarks one or more external command lists and returns process timing statistics in milliseconds.

Process definitions

Every process is a list whose first element is the executable and whose remaining elements are its arguments. Commands are launched directly rather than interpreted by a shell. A map preserves names in the returned results; a list returns results in the same order. Warm-ups default to 2 and measured runs default to 10.

$processes = [
  "Python" => ["python3", "standard-algorithms.py"],
  "PHP" => ["php", "standard-algorithms.php"],
  "ZPEX" => ["zpex", "-r", "standard-algorithms.yas"]
]

$results = Utilities::benchmark($processes, 2, 10)
print($results["ZPEX"]["median"])

Return value

Each process result contains process-total minimum, median, mean, maximum and samples values in milliseconds, plus warmups, runs and the final captured output. When output contains Timer finished: ...ms or Execution completed in ...ms, an additional internal or reported summary is included.
