Is FastFunction like Loop?

[Blizna]

Im wondering if calling FastFunction is like loops, also the app is stopped and the right function is found.

Also, I have very complex and variable system, is FF smart enough that if I call blank function (name="") it even doesnt start?

Is FF faster then MMF true events? I mean is faster:

1)
Event 1 -do smth
Event 2 -do smth + calculate expression

or

2) Event 1 + run FF
On Function: calculate expression

Is 2 faster then 1? Thanks )

Fast Function uses exactly the same system as both true events and loops.

1 is faster than 2. Anything internal to MMF2 is usually faster than extensions.
