PHP 5 uses more RAM than PHP 4, both to start up, and on a
script-for-script basis.

It has more features, more OO complexity, and uses more RAM, plain and
simple.

The PHP Dev Team increased the default/recommended memory limit from 8
M to 16 M with the release of PHP 5.

I think they even documented this change, but you'll have to dig that
out for yourself.

Your hosting company probably kept the old php.ini without realizing
that they needed to read the docs and change it.

ymmv
