Tried 2 more tiffs (but from the same 'source'). They gave the similar
results for relative performance. 1 (0.94) vs 30 (0.95beta) vs
6(0.95beta-jeremias-tiff)
Given my non existent knowledge on tiff (and image formats in general)
and (I am sure recognizable) chronic lack of time to dive into image
formats at this moment, I am afraid I would not even know with which
tiff parameters to play
Perhaps there is some part of the fop/batik tests that could be used
to do some performance regression measurements?
Thanks again for your support!

According to what I found, the problem could be not so much JAI
ImageIO itself, but the codecs.
Apparently, Apple does not provide native codecs for all formats,
(After some more reading) They do for a TIFF reader, however...
maybe their native codec is simply much slower than XG's. ;-)
Another reason could be that their native TIFF reader somehow does
not qualify...
Have you tried using other TIFFs, with different properties? Try
opening in Preview, and Export to TIFF, and modify a few.
Cheers
