At current level of development, on modern multicore CPU Zstandard is faster than Brotli if multithreading option for its ZSTD binary is enabled - while provided compression level is quite similar. If you like Keka just give it some , get it from the App Store or send a PayPal tip! If you buy Keka from the App Store you will be supporting development, IMO: Lz4 is a quick-win compression ("stolen" from deflate), LZMA is the compression at all costs, brotli is the static content compression and zstd is the "balanced" compression (role deflate has now). For this reason we excluded algorithms like lz4 and zstd from this study. You can have a single btrfs mount point that has some files that are uncompressed, some that are compressed with LZO, some with ZLIB, for instance (though you may not want it that way, it is supported).

For the dataset and constraints we were working with, loading the Parquet format file required low CPU utilization and lesser I/O compared to CSV and GZIP, and occupied a smaller memory footprint on S3 compared to the memory-intensive CSV format. I think gzip's behavior is better, because it's better to have no output file than to have an incomplete or corrupted output file. GZIP is a compression standard. Pigz, pronounced as pig-zee, uses the zlib and pthread libraries and takes full advantage of multiple processors and multiple cores when compressing data. Zstandard (or zstd) is a lossless data compression algorithm developed by Yann Collet at and used in the original ZIP and gzip programs), but faster, especially for decompression. 25 GiB SQL dump; gzip quick.

But if we create a one-time, pre-shared dictionary, with zstd the size drops to 122 KB — taking the original compression ratio from 2. *Exaxtly* the same problem happened about 10 years ago, when RPM switched from using gzip to using xz. Yet zstd still outperformed. Done - you can add and remove devices at runtime while the filesystem is in use, migrating data off the device if necessary. AppImage. The input data is compressed with Facebook's Zstandard algorithm, a new flexible design that at lower compression settings provides faster than Deflate (Gzip / ZIP) performances and at highest compression settings provides compression ratio comparable with 7-Zip's LZMA (.
