179 ZLIB compression is the standard compression used by Squashfs
180 file systems. It offers a good trade-off between compression
192 compressed with LZ4 compression. LZ4 compression is mainly
207 compressed with LZO compression. LZO compression is mainly
222 compressed with XZ compression. XZ gives better compression than
223 the default zlib compression, at the expense of greater CPU and
237 compressed with ZSTD compression. ZSTD gives better compression than
