Creating a new php script

I am creating a new PHP script, in the index page it has almost 20 functions, and i tested it on apache and its works really fast, less than 0,01 secs to load, but of course it is localhost. Later i tried on a FREE hosting, and it didnt load anything, google just said "waiting for page" and it was like that for almost 5 minutes and then it said that it couldnt find the page.
My doubt is : the page is really slow for having functions ? because i am going to buy a hosting for 1 year and i dont want to pay it for hosting a page that doesnt load..
If you need the functions i'll post some here, if you want
