@mcm: you got me worried. Your test function was clocking a hell lower than
the original script. But then I found out why; one order of magnitude less
(5000 vs 50000). Once that was corrected, you got the exact same clock
times as "my app" (i.e. function directly in the controller). I also
stripped out the logging part making the app just return the result and no
visible changes to the timings happened.
@hh: glad at least we got some grounds to hold on.
@mariano: compiled or not, it doesn't seem to "change" the mean. a compiled
app has just lower variance.
@all: jlundell definitively hit something. Times are much more lower when
threads are 1.
BTW: if I change "originalscript.py" to
# -*- coding: utf-8 -*-
import time
import threading
def test():
start = time.time()
x = 0.0
for i in range(1,50000):
x += (float(i+10)*(i+25)+175.0)/3.14
res = str(time.time()-start)
print "elapsed time: "+ res + '\n'
if __name__ == '__main__':
t = threading.Thread(target=test)
t.start()
t.join()
I'm getting really close timings to "wsgi environment, 1 thread only"
tests, i.e.
0.23 min, 0.26 max, ~0.24 mean
