[SciPy-user] Newbie question on execution time of import scipy

[Travis N. Vaught]

Interestingly I get the following:

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\travis>python
ActivePython 2.2.2 Build 224 (ActiveState Corp.) based on
Python 2.2.2 (#37, Nov 26 2002, 10:24:37) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> s=time.time();import scipy;print time.time()-s
6.45899999142
>>>
^C
C:\Documents and Settings\travis>
C:\Documents and Settings\travis>python
ActivePython 2.2.2 Build 224 (ActiveState Corp.) based on
Python 2.2.2 (#37, Nov 26 2002, 10:24:37) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> s=time.time();import scipy;print time.time()-s
1.19200003147
>>>

This is using:
Intel Pentium III processor
698 MHz
256 MB of RAM

Weird, huh?

BTW the scipy version is:
>>> scipy.__version__
'0.2.0_alpha_154.4535'
>>>

I then upgraded to the latest build for Python 2.2 and got the
following:

ActivePython 2.2.2 Build 224 (ActiveState Corp.) based on
Python 2.2.2 (#37, Nov 26 2002, 10:24:37) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> s=time.time();import scipy;print time.time()-s
5.09800004959
>>> ^Z

C:\Documents and Settings\travis>python
ActivePython 2.2.2 Build 224 (ActiveState Corp.) based on
Python 2.2.2 (#37, Nov 26 2002, 10:24:37) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> s=time.time();import scipy;print time.time()-s
1.38199996948
>>>

This is with:
>>> scipy.__version__
'0.2.0_alpha_182.4038'

Hope this provides some insight.
