Hi,
I think that the "update" call doesn't necessarly reflect what is slowing it down. I would further debug this and see what actions you are using at the time. It's very likely ( combinned with what alex said about console) that one of the action you use is causing the slow down because using an aap call from Unity that is slow itself. It happens quite a lot.
Have you profiled when published? also try to profile, with Nothin but the game view and the profiler view in your Unit yLayout ( I saved one layout like that) as it will give you a much better idea without the editors being too much in the way.
Bye,
Jean
