Hi there.

As part of initial Integration Testing LibRaw 0.22 with my application, I came across an issue whereby this new version unpacks (before Demosaicing) FujiFilm GFX-100 II images almost 10 X slower than version 0.21.5. I've benchmarked other Camera formats and not seen such a difference. Reviewing the Release Notes I see the GFX100-II is now officially supported. I notice a very subtle difference between the .22 and .2.5 outputs, but clearly there is nothing to explain such a huge difference in performance.

I'll triple check my compilation setting and eventually go through the Libraw Repo and Diff the relevant FujiFilm source files, but the question to ask at this stage is a reason why I see such a disparity in performance between versions, specifically for GFX100-II images? Did the RAF file decoder change radically?

Any help would be appreciated.

Regards,

Sean.
