*Decoding* process is very simple and limited to file (disk) bandwidth.
Postprocessing (demosaicing, color conversion, noise suppression etc) is another story. GPU may help a lot. On the other side, only very good quality postprocessing code should be accelerated, there is no need to very fast and very bad postprocessing. We think, that current LibRaw postprocessing implementation is bad enough....
