Multiplayer low frame rate

Hi.
I’m trying to create a simple multiplayer game, so i followed these tutorials : http://www.youtube.com/watch?v=aqbato9Y7vY and http://unity3d.com/support/resources/tutorials/iphone-multiplayer-tutorial.html
So when i build and run my project fps is about 800 but when i start the server it becomes about 100 and keeps falling.
So i’m interested i’ve made something wrong.

It’s practicly impossible for us to help you. I suggest you do some debugging and see where the problem might be coming from.

You probably have something goofy in the Update function of some server code.
