In 710 the default compression for splitted-out basesfs is "gzip". The resulting basesfs is bigger (about 150% - 200% larger) compard to xz compression used in older Fatdogs, but the actual splitting process is about 4x (that is, 400%) faster.
If small size is really what you're after, you can always run the splitter like this:
Code: Select all
BASESFS_COMPRESSION="-comp xz" fatdog-split-initrd.sh ...
