Because complex handlers were optimized.

Cant this optimization be used without turn on complexity?

Several simple handlers (complexity = 0%) work like this:

handler1
jmp handler2
handler2
jmp handler3
...
handlerN
jmp next_handler

Complex handler that contains handler1…N works like this:

handler1
handler2
...
handlerN
jmp next_handler

So the complex handler doesn’t load addresses of handler2..N and it works faster than sum of handler1..N.
