I only tried "identify" which extracts all kind of information but takes about a second on my computer for a single file which is certainly too much if I want to use it on many files. Perhaps there is some way to extract only part of the exif data (I am only interested in a small part of it anyway) and do it quicker.
exiftool seems to be quicker. Perhaps exifprobe could be helpful as well.
