If I use the old missings choice, that brings me back to the
question about compression, because:
- old missings, compression level 0, gdtb: 25900KB

How is this same number of KB possible?
That'll happen if, when minimal (> 0) computational resources are
devoted to finding matching strings across successive 32k blocks of
data, nothing useful is found. See Mark Adler's response at
But you should examine the size of the output at byte resolution
rather than KB to see if there's really any difference.
