Compression formats compared in this benchmark. Zstd is overall faster, but it is due to its multi-threading capabilities that Brotli lacks.
Running in a single thread, Zstandard is faster for low compression levels, slower at high compression levels. Zstandard decompression is always faster than Brotli ones. With both algorithms using same window size MB and running in a single thread, Brotli provides a minimum compression faster that Zstandard but inferior for compression ratio and Zstandard provides a better maximum compression but slower. This is a clear win for Zstd, providing 22 MB smaller output in less than half the time, speed advantage is consistently reduced in single thread mode.
With same window size MBBrotli surpasses Zstandard in single-threaded speed, but output size advantage for Zstd increases to 66 MB. This use case shows a consistent advantage for Zstandard, creating a 10 MB smaller output in a quarter of the time needed by Brotly to complete same test, and still twice faster running in a single thread. Using same window size for the two algorithms, both size and speed advantages for Zstandard are reduced.
Zstandard beats Brotli for maximum compression by a 20 MB margin, comparing the speed of the two algorithms in this case Brotli which is single threaded is slower if compared with multi-threaded Zstd result, but faster if compared with single threaded result.
With a fixed window size for both algorithms, Zstd preserve its 20 MB difference on output size, and while Brotli remains faster its speed advantage is proportionally reduced over Zstandard.
Fast compression: Brotli, Zstandard comparative speed, performances test. Find out what is the more efficient algorithm between Brotli and Zstandard in terms of speed and compression ratio, at different compression settings ranging from minimum to maximum.

It joins all compressors into a single exe. At the beginning an input file is read to memory. Then all compressors are used to compress and decompress the file and decompressed file is verified. This approach has a big advantage of using the same compiler with the same optimizations for all compressors.
The disadvantage is that it requires source code of each compressor therefore Slug or lzturbo are not included. The default linking for Linux is dynamic and static for Windows. For information about the security of the various compressors, see the CompFuzz Results page. The following results are obtained with lzbench 1.

Zstandardor 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. Should your project require another programming language, a list of known ports and bindings is provided on Zstandard homepage.
For reference, several fast compression algorithms were tested and compared on a server running Arch Linux Linux version 5. Zstd can also offer stronger compression ratios at the cost of compression speed. Speed vs Compression trade-off is configurable by small increments. Decompression speed is preserved and remains roughly the same at all settings, a property shared by most LZ compression algorithms, such as zlib or lzma.
The following tests were run on a server running Linux Debian Linux version 4. A few other algorithms can produce higher compression ratios at slower speeds, falling outside of the graph. For a larger picture including slow modes, click on this link. Previous charts provide results applicable to typical file and stream scenarios several MB.
Small data comes with different perspectives.
The smaller the amount of data to compress, the more difficult it is to compress. This problem is common to all compression algorithms, and reason is, compression algorithms learn from past data how to compress future data. But at the beginning of a new data set, there is no "past" to build upon.
To solve this situation, Zstd offers a training modewhich can be used to tune the algorithm for a selected type of data. Training Zstandard is achieved by providing it with a few samples one file per sample. The result of this training is stored in a file called "dictionary", which must be loaded before compression and decompression. Using this dictionary, the compression ratio achievable on small data improves dramatically.
The following example uses the github-users sample setcreated from github public API. It consists of roughly 10K records weighing about 1KB each.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 Zstandard was designed to give a compression ratio comparable to that of the DEFLATE algorithm developed in and used in the original ZIP and gzip programsbut faster, especially for decompression.
It is tunable with compression levels ranging from negative 5 fastest  to 22 slowest in compression speed, but best compression ratio. The zstd package includes parallel multi-threaded implementations of both compression and decompression.
Starting from version 1. Zstd at its maximum compression level gives a compression ratio close to lzmalzhamand ppmxand performs better than lzaor bzip2. Dictionaries can have a large impact on the compression ratio of small files, so Zstandard can use a user-provided compression dictionary.
It also offers a training mode, able to generate a dictionary from a set of samples. Zstandard combines a dictionary-matching stage LZ77 with a large search window and a fast entropy coding stage, using both Finite State Entropy a fast tabled version of ANS, tANSused for entries in the Sequences sectionand Huffman coding used for entries in the Literals section. Because of the way that FSE carries over state between symbols, decompression involves processing symbols within the Sequences section of each block in reverse order from last to first.
The Linux kernel has included Zstandard since November version 4. In MarchCanonical tested  the use of zstd as a deb package compression method by default for the Ubuntu Linux distribution. Debian developer Ian Jackson favored waiting several years before official adoption. Arch Linux added support for zstd as a package compression method in October with the release of the pacman 5. Arch uses zstd -c -T0 --ultra -the size of all compressed packages combined increased by 0.
Full implementation of the algorithm with an option to choose the compression level is used in the. XCZ  file formats, developed by the homebrew community for the Nintendo Switch hybrid game console. From version 1. From Wikipedia, the free encyclopedia. Lossless compression algorithm.Milwaukee is currently the brushless power tool leader, and offers a range of M12 and M18 Fuel drills and drivers. New brushless saws, a grinder, and heavy duty impacts are coming soon.
Other brands are pushing the brushless envelope further, such as Makita with their automatic down-shifting impact driver. Expect to see new brushless drills and drivers from other brands this Fall. With their premium cordless drill and hammer drill, the emphasis seems to be more on power and the 3-speed gearbox.Real-world HTTP performance benchmarking, lessons learned - Julien Viet
Current 20V Max premium drill users who want more runtime are probably more likely to upgrade to a higher capacity battery than to upgrade their still-relatively-new tools.
I would even bet that prototypes have been developed and are currently being tested. Although, they probably already are losing market share to Milwaukee. A while back I posted about how Dewalt and other brands were slinging mud against each other through YouTube videos. They have to be. Brushless is too big of an influential marketing keyword for brands to ignore. Milwaukee pushed the boundary, and Dewalt and other brands will have to respond accordingly.
Otherwise their brushed-motor cordless tools will look stale and outdated to users accustomed to be seeing heavy marketing that lauds the benefit of brushless motors. For instance, Dewalt has been advertising their compact brushless drills as EXTREME RUNTIME!.
I have discussed this before, but there will always be better tools on the horizon. They could be improved in regard online c compiler download size, weight and runtime, which are all aspects where a brushless motor upgrade might be able to help.
There could be challenges in improving runtime, as well as reducing tool size and weight, without diminishing peak power output. Cost is another potential issue.
My only qualm is battery life, and the 4. Jason saysAug 9, 2013 at 5:19 pmDewalt should have pushed the changer over from stem-pack to slide packs sooner it should have been 2-3 years before the actual 20v line release. I really think they should have made stem pack to slide pack adapters. Jason saysAug 9, 2013 at 5:07 pmI think it might be awhile before we see an update on the premium drill.
The market has been pushing for lighter tools with better run time. I had that Dewalt Premium drill for awhile before I jumped on the Fuel bandwagon that drill is just so big and heavy. I think we might even see Milwaukee release a compact Fuel drill like the Dewalt brushless that is out now if you look at the Dewalt compact brushless drill and Fuel drill side by side the Dewalt looks tiny next to it and its a good pound lighter than the M18 fuel.Jonah was the Co-Founder and CEO of Moat, which was acquired by Oracle in April 2017.
