Dear all,

I was trying to use Mathematica 7.0.1 for batch image processing.  I
used the Import command to load 4000x2000 pixel tiff files.  Using the
timing command, I noticed it takes about 0.95 second just to load the
image !!!!  Using another system, I can do the same in about 0.15 s.  (about
6-7 x faster).

Is there any way to speed things up ???  I already tried to first
write the tiff image data as a raw binary file and loading it again.
It still take about 0.7 seconds in that case.

Thanks in advance,

Peter
