I believe in followup it seemed that the issue was particular to the way some jpeg2000 files were created and how the kakadu library accesses them. No apparent action due within GDAL.

I have confirmed that the trunk and 1.4-esri branch already have optimized dataset level RasterIO() calls for NITFdatasets to the jp2kak driver - so I'm not exactly sure why performance is reported to be poor. Following up on details.
