Animator Setting for AI?

I just make an animator to control characters AI behavior, a pure true/false flow chart without animation.

The problem is I find it slower than my full script version I made before.. In the full script version, character attack immediately after another attack, but this animator version delay like 2 sec.

I can see how the animator state flow on inspector in running, a bit slow....

So, I wonder is there any specific setting for the state machine and transition in AI application? such as exit time 0? transition duration 0? speed 1000 etc
