These regular expressions won't match many file names, which
explains why you notice the speedup. You need to escape the
parentheses twice, once for the string, and once for the regular
expression engine.

I.e.
"\\.\\(?:\\(?:M[Pp]\\|mp\\)3\\)"
"\\.\\(?:O\\(?:GG\\|gg\\)\\|ogg\\)"

Sorry for not noticing this when you asked on the channel.
