Greg,

Could you test again with the trunk version of GDAL (or a daily snapshot of trunk).

Some substantial rewriting of the JP2KAK driver was done in an effort to optimize several cases.

    initial v1  
    1 {{{
    21Conversion from GeoJP2 to GeoTIF with JP2KAK Kakadu based JP2 driver exceptionally slow
    32
    … …  
    76
    87Doing a conversion from GeoJP2 to GeoTIF using the GDAL JPEG2000 JasPer driver, which does use not hardware acceleration, is inexplicably twice as fast as asking the GDAL JP2KAK Kakadu driver, which does use AltiVec and SSE hardware acceleration, to do the same conversion.  This is illogical.
