Both languages have ways around this problem.  mod_perl is the way you
do it for Perl.  When you start up Apache, it runs up a set number of
threads to handle incoming connections.  The Perl is compiled only
once and the compiled code is re-used for subsequent incoming
connections.

Of course this also means you have to be a bit stricter with your
code.  Variables, for example, must be initialised or you'll get the
values from the last time around.

If the designers of X-windows built cars, there would
be no fewer than five steering wheels hidden about the
cockpit, none of which followed the same prinicples --
but you'd be able to shift gears with your car stereo.
Useful feature, that.
