PHP: Why not so fast ?

I have a PHP script that runs fast on a 2008 Mac Book
Pro Laptop but it runs very slow on a brand new Dell
desktop. If the PHP environments are the same and I am
not using servers what else could be affecting the Dell to
make PHP run 2-3 times slower than on the MAC

Details: The PHP working environments are exactly the
same i.e. both PHP.ini files are the same, extensions
used are the same ect…No it does not involve network
connections or database use. There is no out put from
other programs and no PHP userland. I have the exact
same PHP versions 5.2.9 and same exact extension are
installed. I execute PHP scripts from the MSDOS
command line interface. Not using any servers.
What the PHP script does is it copies the information from
several files into one file. It then reads that information
into an array and uses array_count_values to set up an
array_key_exists search. If it is found number is
appended to a file. The data sets are about a million
numbers and this is repeated about 150 times.

Any suggestions to speed up the PHP on the Dell
computer would be greatly appreciated. ::slight_smile:
