On my Ultra 20 box, the test program takes 0.00039982 secs in a terminal window and 0.236839 secs in IDLE, i.e. about 600x slower. This is ActivePython 2.4.3 for Solaris 10 on a 2+ GHz Opteron.
A partial explanation for the difference in run time between terminal and IDLE is that IDLE uses thru a Tkinter/Tcl/Tk window which postprocesses the output, like colorizing, etc. /Jean Brouwers PS) On MacOS X 10.3.9 and a 400 MHz G4 the terminal time is 0.172556 secs and IDLE takes between 4.04731 and 4.87804 secs (depending on the options selected) or 24-28x longer . This is Python 2.4.3, IDLE 1.1.3 and Tcl/Tk 8.4.13 as distributed with MacOS X. sam wrote: > hi all, > > i continue to footle around on my spanking new ultra 20 (1.8GHz / > Opteron Model 144), gradually trying to get to grips with python and > unix both. > > the slow print time in IDLE had already struck me as rather odd. > running programs with heavy print requirements from the terminal was a > major discovery though, printing being so fast as to make everything > appear at once except in the case of literally thousands of items to be > printed. > > test case: > > import time > > time1 = time.time() > for i in range(100): > print 'go get \'em, son!' > time2 = time.time() > > print time2-time1 > > > in IDLE: > 4.433 seconds > > in terminal: > 0.001 seconds > > a difference of between 3 and 4 orders of magnitude is rather striking. > anyone know what's going on here? is it a python, a unix thing, or > something else? > > sam -- http://mail.python.org/mailman/listinfo/python-list
