Comodo FireWall game upload speed slow

Hello so I am hosting games on warcraft 3 frozen throne. But when people are downloading the map file from me it goes slow for such a small map compared to the other games that I join when I download maps. When we get in the game there is not any lag or anything but just that they download the maps slow. So I was wondering if there is a way to configure comodo firewall so that when I host my wc3 games so that people download the map faster? Also I have the ports forwarded.
