40 +Lzip data compression in Linux
41 +==============================
42 +
43 +Linux already offers a lot of compression formats. Then, why lzip?
44 +
45 +Because lzip is the only gzip-like LZMA compressor featuring a
46 +well-designed format:
47 +
48 + * Lzma-alone is a toy format lacking integrity checking or even a
49 + proper header.
50 +
51 + * Xz has a complex and not properly designed format[1]. It can
52 + compress the kernel image a little more than lzip on some
53 + architectures (about 4% on x86) by using a different binary filter
54 + for each architecture. But this increase in complexity does not
55 + improve the decompression time (much less the boot time) compared
56 + with lzip.
57 +
58 + Also the xz compressor is the only one needing special options to
59 + compress data for linux, and xz decompression is the only one that
60 + may fail because of wrong options used at compression time.
61 +
62 + [1] See http://www.nongnu.org/lzip/xz_inadequate.html
63 +
64 +I have the hope that lzma-alone and xz will be eventually abandoned in
65 +favor of lzip.
66 +
67 +Lzip-compressed kernel images of multiple linux versions since 2.6.30.10
68 +have been built and tested, even on machines as modest as an AMD 486-DX2
69 +at 66 MHz with 64 MiB of RAM. In the worst case (on the slow machine
70 +above), lzip just increased the boot time a 15% compared with gzip. On
71 +more modern machines, lzip may boot slightly faster than gzip. It just
72 +takes 0.2 seconds for lzip to decompress vmlinuz-4.4.16 on my machine.
73 +
74 +One little-publicized fact is that, except on embedded systems with fast
75 +boot setups, decompression speed is not important in booting linux.
76 +Decompression time is usually a small fraction of the total boot time.
77 +For example, using lz4 on a desktop machine in order to save 0.05
78 +seconds of a total boot time of 20 seconds is probably not worth the
79 +increased image size.
80 +
