How to accelerate the action

BSZKRPHZ7PW0(1)MYO7GTWS

There are three step action,I want to response step by step, not wait the all result.

And is there else way to accelerate the action response time? I need help,thanks

I mean the custom action.py function time. it takes more than 2 seconds. I test when only have the utter_XX; it run fast.

I test, the action respnse slow, when input a question: time is 13.01.56

Then 13.02.00 it respnse, it slow ,takes me 4 seconds; but in during the function,it fast, you can see,13.02.00,859 ; 13.02.00,859 ; 13.02.00,859

so how to accelerate the time of start up the action function
