Hi, 

There is absolutely something basically wrong.  For that little files conversion
to GeoTIFF should take perhaps 5 minutes.  Try skipping more drivers and see how
Kakadu driver performs.  If you want to know how fast it can be, download Kakadu
win32 executables from www.kakadusoftware.com and measure how long it takes to
expand your images to GeoTIFFs with kdu_expand.
