That loop will take noticably longer than one second, due partly to the unnecessary external command.

NAME
Xacobeo::Timer - A custom made timer. SYNOPSIS
use Xacobeo::Timer; # As a one time use my $timer = Xacobeo::Timer->start("Long operation"); do_long_operation(); $timer->elapsed(); # Displays the time elapsed # A simple stop watch (the destructor displays the time elapsed) my $TIMER = Xacobeo::Timer->new("Method calls"); sub hotspot { $TIMER->start(); # Very slow stuff here $TIMER->stop(); } DESCRIPTION
This package provides a very simple timer. This timer is used for finding hot spots in the application. The timer is quite simple it provides the method "start" that starts the timer and the method "stop" that stops the timer and accumulates the elapsed time. The method "show" can be used to print the time elapsed so far while the method "elapsed" returns the time elapsed so far. When an instance of this class dies (because it was undefed or collected by the garbage collector) the builtin Perl desctrutor will automatically call the method "show". But if the method show or elapsed was called during the lifetime of the instance then the destructor will not invoke the method show. METHODS
The package defines the following methods: new Creates a new Timer. Parameters: o $name (Optional) The name of the timer. start Starts the timer. If this sub is called without a blessed instance then a new Timer will be created. Parameters: o $name (optional) The name is used only when called without a blessed instance. stop Stops the timer and adds accumulates the elapsed time. If the timer wasn't started previously this results in a no-op. show Prints the elapsed time. This method stops the timer if it was started previously and wasn't stopped. elapsed Returns the total time elapsed so far. If the timer was already started the pending time will not be taking into account. AUTHORS
