Hi Mike,

The exiftool script does have powerful multi-file processing abilities. A daemon would only be useful if you want interactive processing of multiple files. Right now to do this you would need to write your own script using calls to the ExifTool functions. It wouldn't be too difficult to set this up if you know a bit of Perl, and would definitely avoid the start-up cost of loading Perl, ExifTool and all the associated libraries. But in the end I'm not sure how much this will speed things up. You could run some tests on your system by processing a large number of files in a single directory to see if the speed benefits will be worth it.

Exiftool used to be a lot quicker, but for each new piece of information that it extracts, it slows down just a little bit more. And now the amount of information extracted from some images is really crazy.
