It calls two external programs in the background: "find" and "sort". You
will get caught if you use a non-Linux web host, as it may not have these
installed. Even other Unix flavours may cause problems as it specifically
relies on the GNU version of "find". (Non-Linux machines usually have the
BSD version of "find".)

It probably will be: particularly for larger directories. "find" and
"sort" are written in C by some very smart people who have optimised them
very well.
