Not yet a big specialist of PHP, but a rule that apply to nearly all server side scripting languages, use global variables as less as you can.
They simplify your programer's life, but on a server that is serving a lot of concurent sessions, it eats all the performances and ressources. It does not explain your time problem, but it is my 2 cents before you place to much stuff in global variables.
