Performance Tuning

I am using Freepbx14/Asterisk 13.21.1. I’ve been looking into to see if it can help some spiking issues with asterisk and help with these messages:

taskprocessor.c:895 taskprocessor_push: The 'subm:manager_topic-00000007' task processor queue reached 3000 scheduled tasks again.

I am however having trouble finding the settings anywhere in etc/asterisk/*. I am starting to wonder if these settings have not been changed at all by the Freepbx Dev’s and they are using the default values of ???. Where can I view, or what command can display, the current/default values of the settings listed in performance tuning?
