And in addition to all that everyone else has said.... most of this is 
startup time.  The python interpreter is a fair bit slower to start up 
(i.e. does much more at startup time) than the perl one:

[on a fairly fast Solaris box].  This is mainly because much more of 
python is written in python and needs to be loaded / dynamically linked 
when the process starts up.  On my system, python loads 14 .so files and 
13 .pyc files.  Perl loads 7 .so files.
