As i know the mirc notify is working with /watch command of the server i have not seen this problem into any of my server's using, there are 2 way's to slow the notify 1: your internet connection speed, 2: server lag , i am not sure but there is not an way to speed an event the event is working when the event HAPPENS then START trigger so if the server is slow response on your /watch command so the trigger slow's too, i am not sure this is my theory.
