Is there a way to speed up EXIF extraction?

If I currently do:-
identify -ping -format "%[exif:*]" <file>

The response is quite slow, seemingly in proportion to the image size.

Is there a way of getting the EXIF tags quicker?

With identify, you have to specify "-ping" after the "-format" option, to be quicker: And you could also use that - for JPG files: It probably won't be as quick as with "-ping" and it's not needed in your example, but it may be useful if you want other image properties (where "-ping" might not be appropriate).

identify -format "%[exif:*]" -ping <file>

identify -define jpeg:size=64x64 -format "%[exif:*]" <file>

What a WORLD of difference! Adding the -ping in the right place makes if multiple times faster!!! THANKS!!!
