So you might want to consider using zstd instead of lzma if you'd like to optimize for file system performance. It's also the default compression used by mkdwarfs. Now here's a comparison with the SquashFS filesystem: $ hyperfine -c 'sudo umount mnt' -p 'umount mnt; dwarfs perl-insta...
设置为“None”表示无解压缩。也可以是一个dict,其中键“method”设置为{'zip',gzip',bz2',zstd}之一,其他键值对被转发到zipfile。ZipFile,gzip。gzip文件,bz2。BZ2文件或zstandard。ZstdDecompressor。例如,可以使用自定义压缩字典为Zstandard解压缩传递以下内容:compression={'method':'zstd','dict_data':my_compr...
Many compression and predictor schemes are supported via the imagecodecs library, including LZW, PackBits, Deflate, PIXTIFF, LZMA, LERC, Zstd, JPEG (8 and 12-bit, lossless), JPEG 2000, JPEG XR, JPEG XL, WebP, PNG, EER, Jetraw, 24-bit floating-point, and horizontal differencing. Tifff...

If set to 'infer', the method detects compression type from the file extensions like .gz, .bz2, .zip, and more. You can also pass a dictionary to customize compression methods such as gzip, zip, bz2, zstd, etc. If set to None, no compression is applied. storage_options: A ...
