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.

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).
