Hi Even,
I was thinking about your request to decode only a sub-window inside of a
tile.
I don't think this is possible. Because of the serial nature the j2k
decoding,
there is no performance gain to only looking at a sub-window - the whole
tile must be
decoded. The only small gain is in memory

Hi Predator,
I have no experience about gdal MinGW build,
but normally, I execute "strip *.dll" after "make install".
https://github.com/sanak/pgrouting4w/blob/master4w/BUILD.mingw#L142
Could you try to do that ?

Hi Aaron & Even,
Decoding at preccints level in OpenJPEG would definitely be a great
addition.
I believe OpenJPEG performance could also be improved if multi-threading
was managed directly inside the lib, since in the current situation
OpenJPEG is purely monothreaded.
From my experience, Kak
Thanks for replies.
Did you use standard commands (./configure, make, make install), or have you
changed something?
What about makefile or config file? Did you apply any changes to them?
