Slowing down my internet connection

Hi All

Hope someone can help me.

The problem I am having with openfire is that is slows down the internet at the server it is installed on. When I do a standard ping test to google I run 178ms but when openfire is active it slows down to about 3879ms the same ping test. All test's that I ran shows that all the lines are correct. Not using the fire wall just to much problems with it then. (no one can access it even with all ports open)

Thanks
