[gdal-dev] NITF read slow in python

[John_Lunzer]

I have some not so big NITF files (10000x7000 16bit) that I am reading using
Python. Using the ReadAsArray() method of the data opened via gdal.Open() it
takes about 50 seconds to load a single band. Reading this same file in
GeoTIFF format takes about 2.7 seconds by comparison. 

Does anyone have a clue why the NITF files are taking so much time to read
to Numpy arrays?
