This same program in interpreted C# or Java (as opposed to JITed) runs
about the same speed as CPython (~110ms on my machine). IronPython
takes almost 3 seconds in the inner loops. Any ideas why?
IronPy version:
------------------------
import System
kTotalReps = 800
kNumReps = 100
start = System.Environment.TickCount
blah = 0
randgen = System.Random()
highnum = 0.0
for i in range(kTotalReps):
myt = []
for j in range(kNumReps):
toadd = randgen.NextDouble()
myt.append(toadd)
highnum = max(highnum, toadd)
blah = blah + 1
print blah
print highnum
print (System.Environment.TickCount-start)
----------------------
CPy version:
----------------------
import time
import random
kTotalReps = 800
kNumReps = 100
start = time.time()
blah = 0
highnum = 0.0
for i in range(kTotalReps):
myt = []
for j in range(kNumReps):
toadd = random.random()
myt.append(toadd)
highnum = max(highnum, toadd)
blah = blah + 1
print blah
print highnum
print (time.time()-start)*1000
