Any of the -X operators involve a call to stat(). You can use the cached result by doing if -f $_ and ! -l _ ie the '_' char accesses the (last) cached stat result. As for readdir vs glob I would expect them to be similar for speed. glob *is* different from readdir in one important way that can bite you if you don't expect it. With glob you will have the full/partial path you fed it in every result element. Sometimes this is very convenient as it saves adding the path, sometimes of course it is not. If it is convenient I use glob, if I just want the file/dir names without any path I use readdir.
