Just to comment on this, my friend in the computer game industry insists
that compression begets speed in almost all data handling situations.
This will be worth bearing in mind as we start to have more fine-sliced
Pilatus 6M (or similar) datasets to deal with.
Cheers,
David.

Subject: [ccp4bb] I compressed my images by ~ a factor of two, and they
load and process in mosflm faster
If you have OS X 10.6, this will impress your friends and save you some
disk space:
% du -h -d 1 mydata
3.5G mydata
mv mydata mydata.1
sudo ditto --hfsCompression mydata.1 mydata rm -rf mydata.1
% du -h -d 1 mydata
1.8G mydata
This does hfs filesystem compression, so the images are still recognized
by mosflm, et al. I think they process a bit faster too, because half
the information is packed into the resource fork.
