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)
