Zstandard (also known as zstd) is a free open source, fast real-time data compression program with better compression ratios, developed by Facebook. It is a lossless compression algorithm written in C (there is a re-implementation in Java) – its thus a native Linux program.

What is the fastest data compression algorithm?
The fastest algorithm, lz4, results in lower compression ratios; xz, which has the highest compression ratio, suffers from a slow compression speed. However, Zstandard, at the default setting, shows substantial improvements in both compression speed and decompression speed, while compressing at the same ratio as zlib.
How do I increase data compression?
Match Compression Type to Data
Varying the type of compression you use can make a large difference. There are two types of compression to select from, lossy and lossless. Lossy compression reduces file sizes by eliminating data to create an approximation of the original file.
Why is ZSTD so fast?
Zstd offers much faster decompression and stronger compression. It also makes better use of larger blocks, so we use 256 KB blocks as a middle ground between miss latency and compressed size. When we switched the HHVM binary and bytecode to zstd, we saw 2x faster reads, and the packages were 15 percent smaller.
What is fast compression?
LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core, scalable with multi-cores CPU. It features an extremely fast decoder, with speed in multiple GB/s per core, typically reaching RAM speed limits on multi-core systems. ... All versions feature the same decompression speed.
What is the best compression algorithm?

Is lz4 lossless?
LZ4 is a lossless data compression algorithm that is focused on compression and decompression speed.
How do you compress data?
Data compression is a process in which the size of a file is reduced by re-encoding the file data to use fewer bits of storage than the original file. A fundamental component of data compression is that the original file can be transferred or stored, recreated, and then used later (with a process called decompression).
What is the purpose of data compression techniques in data communication networks?
The goal of data compression is to represent an information source (e.g. a data file, a speech signal, an image, or a video signal) as accurately as possible using the fewest number of bits.
Is data compression needed?
Why Data Compression is Important
This can result in significant cost savings. Compressed files require significantly less storage capacity than uncompressed files, meaning a significant decrease in expenses for storage. A compressed file also requires less time for transfer while consuming less network bandwidth.
How do you compress in ZSTD?
To compress a file, call the zstd command followed by the -z flag, which tells zstd to do the compression, and finally, the name of the file to compress. For example, the command below compresses the system-backup file into a . zst file. Once the command executes, the file gets compressed and creates a filename .
How do you make ZSTD?
Build instructions
- make install : create and install zstd cli, library and man pages.
- make check : create and run zstd , tests its behavior on local platform.
What is a Zst file?
A ZST file is a file compressed with the Zstandard (zstd) compression algorithm. It contains a file compressed with lossless compression at a level specified by the user. ZST files are used for reducing file sizes for various purposes, such as databases, file systems, networks, and games.
