Yes. Maybe it isn't good to give so clear recommendation for LZO over
gzip here.

I think it is still safe to say that gzip and LZO are better than
bzip2, XZ, or LZMA for compressing a kernel that will be loaded from a
normal hard disk. It would be unusual if reading the disk was so slow
that e.g. XZ would make the booting faster than gzip.
