Comment:

 @dshafik I'm sorry that a full decade has passed with no further response
 to your ticket.

 In the meantime the `apply_filters()` function has seen several
 performance improvements to its internals, including avoiding the call to
 `array_slice()` where possible which was a related bottleneck.

 If someone wants to look into whether there is still a performance
 improvement to be gained here by switching to calling `$func` rather than
 `call_user_func_array()` then we'll need some good benchmarking numbers to
 accompany it, although I suspect that the addition of the `is_callable()`
 check will negate any further micro-optimisations.
