Zstandard, or zstd as short version, is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by Huff0 and FSE library Best decompression speed goes to Facebook's zstd/pzstd and by pigz. At level 9 compression, zstd = 578MB/s, pzstd = 273MB/s and pigz = 326MB/s Multi-threaded compression tools used the most memory for compression with plzip using the most memory followed by px zstd Size 4.2M 5.5M 7.8M 5.8M Compression speed 0.2 MB/s 1.8 MB/s 21.4 MB/s 2.8 MB/s Decompression speed 4.8 MB/s 13.6 MB/s 48.4 MB/s 19.1 MB/ zstd:2 seems like a nice performance point : very little speed impact, with very large savings (compared to lzo). I would also be interested in a read performance graph. It is said that zstd is faster than lzo for read Zstandard (or zstd) is a lossless data compression algorithm developed by Yann Collet at Facebook. Zstd is the reference implementation in C . Version 1 of this implementation was released as free software on 31 August 2016
zstd, the new and trendy kid in town, can easily replace gzip since it offers slightly better compression at speeds that are marginally faster than gzip with the default options. Compression is not at all great when the defaults are used but it does shine when -19 -T0 is used and it is, when configured to use the best compression it offers and all CPU cores, comparable to lzip and xz We ran some additional benchmarks for them and here are our primary takeaways. All three tools are excellent diff engines with clear advantages (especially in speed) over the popular bsdiff. Patch sizes for both binary and text data produced by all three are pretty comparable with Xdelta underperforming Zstd and SmartVersion only slightly . For patch creation speed, Xdelta is the clear winner for text data and Zstd is the clear winner for binary data . And for Patch. Here are some benchmarks of Zstd Btrfs compression compared to the existing LZO and Zlib compression mount options. Facebook's Zstd compression support within the Linux kernel is enabled under Linux 4.14 if the CONFIG_ZSTD_COMPRESS and CONFIG_ZSTD_DECOMPRESS options are enabled
Squash Compression Benchmark. The Squash library is an abstraction layer for compression algorithms, making it trivial to switch between them or write a benchmark which tries them all, which is what you see here! The Squash Compression Benchmark currently consists of 28 datasets, each of which is tested against 29 plugins containing 46. With ZSTD (17) it got down to <600 Megabyte in ~5 Minutes, while DEFLATE never got anywhere near that. Similarly for the big file, ZSTD (17) takes it down to 60 Gigabytes but it took almost 14 hours. DEFLATE capped at 65 Gigabytes. The sweet spot for ZSTD was at 10 with 4 hours for 65 Gigabytes (DEFLATE took 11 hours for that)
Lzturbo library: world's fastest compression library. - Method 1 - compress better, more than 2x faster, decompress 3x faster than Snappy. - Method 1 - compress better and faster, decompress up to 1.8x faster than Lz4. - Method 2 - compress better and 4x faster, decompress 7x! faster than zlib-1 All benchmarks were performed on an Intel E5-2678 v3 running at 2.5 GHz on a Centos 7 machine. Command line tools (zstd and gzip) were built with the system GCC, 4.8.5. Algorithm benchmarks performed by lzbench were built with GCC 6 . In this case, both compression and decompression times are important. You can observe Fast compression algorithms are better than traditional algorithms such as DEFLATE (zlib). ## Documentation The LZ4 block compression format is detailed within [lz4_Block. 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
zstd (zstd) defaults to 1 of 1..21, so its fastest setting, and I'm unsure of why that is. this isn't really a codec.. this is an archiver. lrzip (lrzip) is not a codec but actually a bit of a swiss army knife leveraging tar, lzma, gzip, lzo, bzip2, and zpaq, and a sort of block sorting pre-processing stage zstd is a fast lossless compression algorithm and data compression tool, with command line syntax similar to gzip (1) and xz (1). It is based on the LZ77 family, with further FSE & huff0 entropy stages. zstd offers highly configurable compression speed, with fast modes at > 200 MB/s per code, and strong modes nearing lzma compression ratios ZSTD is actually faster than reading decompressed: significantly less data is coming from the IO subsystem. We know LZ4 is significantly faster than ZSTD on standalone benchmarks: likely bottleneck is ROOT IO API This is the Homepage of 7-Zip with support for: Zstandard. Brotli. Lz4. Lz5. Lizard.

Benchmark code; LZ4 and ZSTD. LZ4 is one of the fastest compressors around, and like all LZ77-type compressors, decompression is even faster. The fst package uses LZ4 to compress and decompress data when lower compression levels are selected (in method write_fst). For higher compression levels, the ZSTD compressor is used, which offers superior compression ratio's but requires more CPU. On one end, zstd level 1 is ~3.4x faster than zlib level 1 while achieving better compression than zlib level 9! That fastest speed is only 2x slower than LZ4 level 1. On the other end of the spectrum, zstd level 22 runs ~1 MB/s slower than LZMA at level 9 and produces a file that is only 2.3% larger

It also features a very fast decoder, with speeds > 500 MB/s per core
ZSTD compression patches have been sent in a number of times over the past few years. Every time, someone asks for benchmarks. Every time, someone is concerned about compression time. Sometimes, someone provides benchmarks. But, as far as I can tell, nobody considered the compression parameters, which have a significant impact on compression time and ratio. So, I did some benchmarks myself. . Seriously, it's a game changer for potential data file transfer speeds! Rsync 3.2.3 Benchmarks. Here's Rsync 3.2.3 with zstd compression fast negative levels for -30, -60, -150, -350 and -8000 to showcase how flexible zstd is in allowing you to choose speed versus compression ratio/sizes. For rsync 3.2.3 zstd there are.
RasterLite2 reference Benchmarks (2019 update) Intended scope In recent years new and innovative lossless compression algorithms have been developed. The current benchmark is intended to check and verify, through practical tests, how these new compression methods do practically perform under the most usual conditions zstd reaches higher compression levels in comparison to lz4. zstd utilizes the CPU more for compression and decompression in comparison to lz4. Greater compression levels can reduce I/O transfer sizes. But, typically, choosing the mid-compression-level is a good choice. In order to help you tune the compression setting for your columnstore indexes, we ran a little test that shows how low vs. This may mean my implementation of the benchmark is faulty, or it may be a fault in the library. I will conduct further tests. For now, I have marked the respective libraries with an asterisk (*). We made a custom demo for . No really. Click here to check it out.

Zswap is a kernel feature that provides a compressed RAM cache for swap pages. Pages which would otherwise be swapped out to disk are instead compressed and stored into a memory pool in RAM. Once the pool is full or the RAM is exhausted, the least recently used page is decompressed and written to disk, as if it had not been intercepted.After the page has been decompressed into the swap cache. zstd(1) User Commands zstd(1) NAME zstd - zstd, zstdmt, unzstd, zstdcat - Compress or decompress .zst files SYNOPSIS zstd [OPTIONS] [-|INPUT-FILE] [-o OUTPUT-FILE] zstdmt is equivalent to zstd-T0 unzstd is equivalent to zstd-d zstdcat is equivalent to zstd-dcf DESCRIPTION zstd is a fast lossless compression algorithm and data compression tool, with command line syntax similar to gzip (1) and. zstd-small: CLI optimized for minimal size; no dictionary builder, no benchmark, and no support for legacy zstd formats; zstd-compress: version of CLI which can only compress into zstd format; zstd-decompress: version of CLI which can only decompress zstd format; Compilation variables. zstd scope can be altered by modifying the following make variables : HAVE_THREAD: multithreading is.

Gzip Level 9 2020-09-18 05:30:03 Remote. LZ based Compression Benchmark on PE Files Zsombor Par oczia Abstract The key element in runtime compression is the compression algorithm itself, that is used during processing. It has to be small in enough in decom-pression bytecode size to t in the nal executable, yet have to provide the best possible compression ratio. In our work we benchmark the top LZ based compression methods on Windows. Our next benchmark measures 100% 8K sequential throughput with a 16T16Q load in 100% read and 100% write operations. Using our HDD configuration (with ZSTD compression), the HPE Microserver Gen10+ TrueNAS was able to reach 41,034 IOPS read and 41,097 IOPS write in SMB and 145,344 IOPS read and 142,554 IOPS read in iSCSI. Switching on. zstd offers a wide variety of compression speed and quality trade-offs. It can compress at speeds approaching lz4, and quality approaching lzma. zstd decompressions at speeds more than twice as fast as zlib, and decompression speed remains roughly the same across all compression levels. Because it is a big win in speed over zlib and in compression ratio over lzo, FB has been using it in. InnoDB, MyRocks and TokuDB on the insert benchmark. This post shows some of the improvements we recently made to RocksDB to reduce response time variance for write-heavy workloads. This work helps RocksDB, MyRocks and MongoRocks. This also extends the result I shared for the impact of the InnoDB redo log size on insert benchmark load throughout
Popularity of zstd is a result of buzz marketting, that's what I meant and I uphold my opinion. I saw the benchmark in this commit message and it's just baloney. Claiming that zstd is as fast as lz4 in decompression and that zstd -16 can compress >8MB/s on 3.1 GHz i7 is just a lie. But they bought it, their choice. Anyway, that's not. Benchmarks. For reference, several fast compression algorithms were tested and compared on a server running Arch Linux (Linux version 5.0.5-arch1-1), with a Core i9-9900K CPU @ 5.0GHz, using lzbench, an open-source in-memory benchmark by @inikep compiled with gcc 8.2.1, on the Silesia compression corpus.
