Given that this is a templating tool, it's probably during render. My guess of what you'd get out of rewriting in C is greater control over string manipulation and related memory allocation. That said, if you're hitting performance issues, I might suggest looking into another templating tool that's more actively maintained. Extensions are generally harder to maintain than userland code. If you succeed in writing a faster version of this tool, this could turn into a "now you have two problems" situation[1]. If at all possible, it'd be better to let an existing community solve performance issues for you. The last question should I use call_user_function or write this function > in C. > Call the internal function directly for less overhead. Hope this helps!
