Preloader coming late

Dear Kirupa and friends,
I am using a simple loop type of code to have a % counter… You know.
The main interface is quite heavy and that’s why I am using it. The script for loading is on the 2 first frames of the main interface.
I don’t understand why this loader is taking a real long time to come up and only shows up at 85 % of the download, making it a bit useless.

with a bit of patience, you’ll see what I’m talking about.
Thanks for suggestions.
