[PyMOL] question about checking the performance of PyMOL

[Joonghyun R. <jh...@vo...>]

Hi, all

I am sending this email for asking you about checking the performance of
PyMOL.
I tried to check the elapsed time for the computation of a molecular surface
as follows.

--
import os
import cmd
import pymol

cmd.set("surface_quality", "2")

start = time.time()
cmd.show("surface")
end = time.time() 
elapsedTime = (end - start)
print "Elapsed time: ", elapsedTime, "sec."

--

The result always shows 0 sec. for any sized PDB file. For example, it takes
about 10 sec. for 1L7A.pdb (by my watch) 
which contains about 5000 atoms. However, if I run the above codes in PyMOL
command-line mode, 
it shows Elapsed time: 0 sec. 

Currently, I am using PyMOL 1.1b4edu (May 2008) on Windows XP.

Should I use other APIs for checking the performance?
