Gzip 1.14 Released With Faster Decompression On Intel & AMD CPUs
Gzip 1.14 released earlier today as the first new release to this widely-used file compression format on Linux systems and other platforms.
Gzip 1.14 has been nearly two years in the making but has just a handful of bug fixes and some other minor alterations. Most notable for users is Gzip 1.14 delivering faster decompression performance on Intel and AMD x86_64 CPUs:
PCLMUL has been around since the Intel Westmere days or on the AMD side since Bulldozer. So basically if your Intel/AMD Linux system is within the past decade or decade and a half old, it will likely have PCLMUL for Carry-Less Multiplication Quadword.
The original patches working on this PCLMUL implementation for Gzip note around a 13% time reduction during decompression.
Those interested in the few other changes of Gzip 1.14 can find the list of patches and download links via the release announcement.

"gzip now decompresses significantly faster by computing CRCs via a slice by 8 algorithm, and faster yet on x86-64 platforms that support pclmul instructions."
