If I use the old missings choice, that brings me back to the
question about compression, because:
- old missings, compression level 0, gdtb: 25900KB
- old missings, compression level 1, 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
https://stackoverflow.com/questions/40595352/compression-ratios-for-diffe...
But you should examine the size of the output at byte resolution
rather than KB to see if there's really any difference.
