90+ seconds?? What hardware, OS, and Python version? What else was
running in the background?
With this kit:
OS Name: Microsoft Windows XP Professional
Version: 5.1.2600 Service Pack 2 Build 2600
Processor: x86 Family 15 Model 36 Stepping 2 AuthenticAMD ~1995 Mhz
Python: Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310
32 bit (Intel)] on win32
and your exact code, I get:
xRange 4.0
Range 5.0
After changing time.time to time.clock, I get:
xRange 4.00560127055
Range 4.8927366467
After making the "benchmark" somewhat more realistic by executing it
inside a function, I get:
xRange 1.86865816745
Range 3.31902658019
By "inside a function", I mean changing
<script>
to
def foo():
<script>
foo()
