So the decision of which algorithm ...LZ4 is a very fast lossless compression algorithm, providing compression speed > 500 MB/s per core, scalable with multi-cores CPU. It also features an extremely fast decoder, with speed in multiple GB/s per core, typically reaching RAM speed limits on multi-core systems. LZ4 is available as a C Open Source project, hosted on Github, under a BSD license.Compression Tests. This test suite consists of tests that measure various forms of file compression such as gzip, bzip2, and 7zip. This suite is good for testing the system's processor, memory, and overall system performance. See how your system performs with this suite using the Phoronix Test Suite.From: Paul Eggleton <[email protected]> To: [email protected] Subject: [PATCH 3/5] poky.yaml: add lz4 and zstd to essential host packages ...[01/17] lib: Add support for ZSTD-compressed kernel. Message ID: [email protected] (mailing list archive) State: Not Applicable: Headers: show brotli - Brotli compression format. ZLib - A massively spiffy yet delicately unobtrusive compression library. 7-Zip-zstd - 7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard. LZHAM - Lossless data compression codec with LZMA-like ratios but 1.5x-8x faster decompression speed, C/C++.As you move from LZ4 through DEFLATE to brotli you layer on more effort to predict and encode data and get more compression out at the cost of some speed. As an aside, algorithms like brotli and zstd can generally outperform gzip--compress better at a given speed, or get the same compression faster--but this isn't actually because zlib did ...Lz4 vs zstd. 30): Greedy parsing with matches found using HC4 matchfinder (hash chains with 4 bytes hashing, plus a table with 3 bytes hashing). lzo, lz4, gzip, bzip2, xz, zstd: gzip, bzip2: Multi-threaded compression to make it faster on computers with multiple cores/cpu: Yes: No: Ability to encrypt the data with a password: Yes: No: Information taken into account to save the filesystem ...Hello everyone, I've written a simple program for backing up full and incremental ZFS snapshots to S3. It supports CRON based scheduling and can automatically remove old snapshots and backups. A helpful CLI ( zfsup) lets you run jobs, restore, and list backups. My goal in writing the program was to take advantage of cheap S3 storage classes ...The Btrfs filesystem supports filesystem-level data compression. When you access the files stored in your Btrfs filesystem, those files' data will be automatically decompressed. This feature of the filesystem will save you a lot of disk space and will save you a lot of time. In this article, how to enable the Btrfs filesystem-level compression on a Btrfs filesystem is explained.How does zstd compare to xz, lz4, gz etc in file size, compress time/ratio etc for different types of data? Here's an interesting comparison . Basically, lz4 can be useful if you want speed above all else, and lzma can be useful if you want the best possible compression, and don't care about decompression speed.It does not compress as well. But ~3.2:1 compression ratio best case for lz4 (listed as ~3.2 in the chart) compresses almost as quickly as the 6:1 zstd [0] but will then decompress twice as fast as zstd at any level [1]. Having a high-compression is a case I could (almost) not care about.Short answer is that ZStd compresses more, but slower. LZ4 is faster. FreeNAS user since 2011 - - Currently Running, TrueNAS 12.0-U2.1 on one server at home and five at work. Show : Emily-NAS. This one was built in 2018, but I reused the name from a previous build. This is the 8th FreeNAS unit I have built for home.lz4 has high throughput, but low compression ratio zstd how good throughput, and good compression ratio. Adding zstd compression to the xprotocol gives the user a good choice over saturated networks with lower CPU costs then deflate, but higher compression ratios than lz4.

LZHAM - Lossless data compression codec with LZMA-like ratios but 1.5x-8x faster decompression speed, C/C++.Modern compression algorithms like zstd can be really fast. For a fairer comparison, I have also included Eric Biggers' libdeflate utility. It comes out ahead of zstd which stresses once more the importance of using good software! gzip. 175 MB/s. gzip (Eric Biggers) 424 MB/s. zstd. 360 MB/s.Zstd, short for Zstandard, is a new lossless compression algorithm, aiming at providing both great compression ratio and speed for your standard compression needs."Standard" translates into everyday situations which neither look for highest possible ratio (which LZMA and ZPAQ cover) nor extreme speeds (which LZ4 covers). It is provided as a BSD-license package, hosted on Github.How does zstd compare to xz, lz4, gz etc in file size, compress time/ratio etc for different types of data? Here's an interesting comparison . Basically, lz4 can be useful if you want speed above all else, and lzma can be useful if you want the best possible compression, and don't care about decompression speed.zstd is a fast compression algorithm that aims to be as efficient (or better) than gzip, but with better speed closer to lz4, relatively. For a long time, the gzip compression algorithm, from levels 1-9, has been serving very good compression ratio compared to many compression algorithms, lz4 included.As you move from LZ4 through DEFLATE to brotli you layer on more effort to predict and encode data and get more compression out at the cost of some speed.
