There's also nothing wrong with using BSD calls: opendir(3), readdir(3), closedir(3). I'd be willing to bet (without empirical data) that those are actually the fastest of any of the proposed options.
Cheers,

Subject: Re: SLOW -[NSFileManager directoryContentsAtPath:matchingExtension:options:keepExtension:]
In that case I suggest you use an FSIterator with
FSGetCatalogInfoBulk(). There have been quite a few posts on this
subject on this list. Search the archives for FSGetCatalogInfoBulk().
FSGetCatalogInfoBulk() is probably the fastest method for directory
enumeration if you need any kind of metadata about the file (name,
directory, permissions, whatever).
Conversely, directoryContentsAtPath is probably the slowest method to
enumerate directories.
