That's assuming 64bit is faster than 32bit... which it isn't

But even if it were, you don't want a 64bit version of perl and python
on a mostly 32bit box.  Trust me; you don't want to mix 32 and 64 with
those languages.  Either you end up with a rats nest of other 64 bit
apps (vim, xchat, gaim, mod_perl, apache -- after all, those link
against perl and/or python, and that means they have to be 64bit also)
or you end up trying somehow to get both a 64bit and a 32bit perl on
the same box (which means maintaining each CPAN module in two places,
etc).  Madness in both directions.

Install the full 64bit distro if you want 64bit, otherwise stick with
