Re: [pygame] Debug printouts - faster to screen or file?

[Pete Shinners <pete@visionart.com>]

ok, ok, to get past our "theoretical" discussion, i wrote a quick and 
simple test. i'm sure results will vary wildly for different platforms, 
but i think we'll see the printing to file is by far the leader..

for a pentium2-300 on winnt 4, i get this:

PERFORMANCE RESULTS
stdout  3.42 seconds
file    0.05 seconds


cheers to modern filesystems and efficient caching :]
i guess i should note this was run in a console window with about 80x40 
characters.
"""test the output speed to various devices"""

import sys, time



def printingtime():
    start = time.time()
    for i in xrange(1000):
        print 'Sometimes we must debug, but where should it go?'
        print '\tThe value of "i" i equal to the value:', i
    end = time.time()
    return end - start



orig_stdout = sys.stdout
time_stdout = printingtime()

sys.stdout = open('debug_stdout.txt', 'w')
time_file = printingtime()


sys.stdout = orig_stdout
print "\nPERFORMANCE RESULTS"
print "stdout  %.2f seconds" % time_stdout
print "file    %.2f seconds" % time_file
