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.

The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more. These APIs include such foundational facilities as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt, login, exit and more.
This package contains libraries for applications to use the QATzip APIs.
Intel(R) QuickAssist Technology (Intel(R) QAT) provides hardware acceleration for offloading security, authentication and compression services from the CPU, thus significantly increasing the performance and efficiency of standard platform solutions. Its services include symmetric encryption and authentication, asymmetric encryption, digital signatures, RSA, DH and ECC, and lossless data compression. This package provides user space libraries that allow access to Intel(R) QuickAssist devices and expose the Intel(R) QuickAssist APIs and sample codes.
Zlib is a free, general-purpose, not covered by any patents, lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms.
