pymel.core.system.timer

static system.timer(*args, **kwargs)

Allow simple timing of scripts and commands. The resolution of this timer is at the level of your OS’s gettimeofday()function. Note:This command does not handle stacked calls. For example, this code below will give an incorrect answer on the second timer -ecall.timer -s; timer -s; timer -e; timer -e; To do this use named timers: timer -s; timer -s -name innerTimer; timer -e -name innerTimer; timer -e; I the -e flag or -lap flag return the time elapsed since the last ‘timer -s’ call.I the -s flag has no return value.

Flags:

Long name (short name)		Argument Types	Properties
endTimer (e)		bool
	Stop the timer and return the time elapsed since the timer was started (in seconds). Once a timer is turned off it no longer exists, though it can be recreated with a new start
lapTime (lap)		bool
	Get the lap time of the timer (time elapsed since start in seconds). Unlike the endflag this keeps the timer running.
name (n)		unicode
	Use a named timer for the operation. If this is omitted then the default timer is assumed. Flag can have multiple arguments, passed either as a tuple or a list.
startTimer (s)		bool
	Start the timer.

Example:

import pymel.core as pm

pm.timer( s=True )
# Result: u"Timer 'defaultTimer' started." #
# code being timed
print "START: time this"
for i in range (0, 50):
    print ("time this "+str(i))
print "END: time this"
pm.timer( e=True )
# Result: 1.729349 #
# Named timers can be used for nesting
pm.timer( s=True, name="outerLoop" )
# Result: u"Timer 'outerLoop' started." #
print "START: macro loop timing"
for i in range(0,50):
    pm.timer( s=True )
    for j in range(5,50):
            newObjs = pm.sphere( spans=j )
            pm.delete( newObjs )
    innerTime = pm.timer( e=True )
    lapTime = pm.timer( lap=True, name="outerLoop" )
    print "\tInner loop %d = %g" % (i, innerTime)
    print "\t       SUB = %g" % lapTime
fullTime = pm.timer( e=True, name="outerLoop" )
print "END: Full timing was %g" % fullTime
