You need to define what you mean by "best". Using gzip9 generally gives the smallest on-disk size but uses significant amounts of CPU time at quite high priority. > Default compression is still lzjb and True >bootloader can't boot oof datasets compressed with lzjb. What gave you that idea? I've been booting FreeBSD off lzjb-compressed pools for something like 5 years. AFAIK, you can't use gzip (or you couldn't when I last tried). -- Peter Jeremy [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.20 (FreeBSD) iEYEARECAAYFAlHfzWIACgkQ/opHv/APuIf5tQCfdOHeXPVkMHs3OhZg+5sjo6aB yqIAoIm805ogYLoNY3w+MT0auU4aqUkR =5Lj4 -----END PGP SIGNATURE-----
