Just look at the ms/frame column of the debug panel to see whats causing slowdowns. The fnc is the time for functions, its not really high right now, no need to optimize that.

You can look up the meaning of all values in the manual under "default.c".
prv is pretty high, srv is normal when i compare it to my projects.
