LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (>0.15 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. LZ4 library is provided as open-source software using a BSD license. This benchmark simulates simple "static content transfer" scenario such as OS Kernel compression or video game's static assets (text/images/tables/scripts/etc) which loading from Flash Memory / HDD / SSD. In this case, compression time is completely ignored. Because only content developers compress the data at once and usually they don't care about its computational cost. But they always care end user's experience a.k.a. "loading time" and bandwidth. Please pay attention to "LZ4HC -9" which is quite faster than other methods.
Features
- LZ4 library is provided as open-source software using BSD 2-Clause license
- Speed can be tuned dynamically, selecting an "acceleration" factor
- LZ4 is also compatible with dictionary compression
- LZ4 is also compatible and optimized for x32 mode
- You can download and install LZ4 using the vcpkg dependency manager
- The LZ4 port in vcpkg is kept up to date by Microsoft team members and community contributors
