Fastest data compression

Best lossless compression algorithms
Conclusion: For 7ZIP use the *. 7z format with LZMA2 and BZIP2 with the "fastest" setting to obtain 50% compression in a reasonable (fastest) amount of time.
Because 7Zip is open source, there should be no issues with compatibilities in the near future..
Best lossless compression algorithms
The 7ZIP algorithms LZMA2 and BZIP2 (implemented as *. 7z file) were the fastest and had a compression time of around 1 minute and decompression times of around 2 minutes (non-threaded)..

LZ4 is lossless compression algorithm, providing compression speed at 400 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.

Overview

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.

Should we use a lossless compression algorithm?

A lossless compression algorithm is useful only when we are more likely to compress certain types of files than others; then the algorithm could be designed to compress those types of data better.
Thus, the main lesson from the argument is not that one risks big losses, but merely that one cannot always win.

What are Genetics compression algorithms?

Genetics compression algorithms (not to be confused with genetic algorithms) are the latest generation of lossless algorithms that compress data (typically sequences of nucleotides) using both conventional compression algorithms and specific algorithms adapted to genetic data.

The first free option in this roundup, 7-Zip is another program with an excellent reputation.
It can handle pretty much any compressed file format you care to throw at it.
A real stalwart of the compression world, 7-Zip boasts its own compressed file format, 7z.

How do compression algorithms affect a file?

Compression algorithms alter files in various ways, such as eliminating the many spaces that appear in documents, crushing bits closer together, removing unnecessary characters, and other methods

For text files, this can lower the size by more than 50%

ZIP files are a common form of compression that is in everyday use

Lossless compression is about removing bits without actually eliminating information,The results of the compression benchmark show that the BrotliStream class was the fastest at compressing the data in the optimal mode. In this mode, the BrotliStream class was able to compress the data in 89.09 ms, while the GZipStream, DeflateStream, and ZLibStream classes took 138.35 ms, 138.54 ms, and 139.66 ms, respectively.
