How to make all available CPU resource to Perl/MySQL in Win XP?

Hi Sorry that this isn't really a 'Perl' problem, although there may be a Perl solution... I am developing a Perl & MySQL application - the problem I have is that the program takes a while to run and yet when I look at the CPU utilisation (with SysInternals Process Explorer) I see that the programs Perl.exe & mysqld-nt.exe are barely using 2% of CPU each.
