Time to send a Access-Accept message

[Kyriaki Gali]

I want to know if freeradius v 1.0.0 need some millisecond to send an access-accept message by default.   I have a script that  needs only 67 ms and when i run it in Radius client test , i see that do more than 500ms to send me an access-accept message! Does anyone know if needs some ms to  send me a message like access-reject message?   Thanks in advance.
