big huge all passes in a exr is slow.   Has to read entire file (75MB+) to
find the channel you want that might be 200KB every single time you want to
deal with that little mask channel.   They also seem to take longer to
render out of 3d.   We usually break them up by math type and try not to
stuff 20 passes into a file.
