Are you using ImageIO to read the image and extract the meta data? If so, ImageIO has optimized native code for most popular image formats on Windows, Solaris and Linux -- but not on OS X. On the Mac ImageIO runs entirely as pure Java, and thus is much slower.

I've been warned about that by another poster. Indeed there's a mix of JPG and "camera raw" files; the latter are read by my own code, which is in pure Java. At this point it's worth while to run some "partitioned" test (i.e. to have figures for each type of file). I'm starting to work at it.


Thanks.
