Fast animation

Hi eberybody,
There is something that I can not undertsand yet. I have published a fla file which is 6 kb size. It is a simple animation and it is really fast when I test it. the problem is that on the server runs slowly so the animation become boring. I thought that maybe it was the server but I have checked the file on my hard disk and runs slow as well…maybe there is something on the html page that is slowing my animation…any suggestion?

thanks in advance
