Big Speed Boost For AES-GCM Performance On Intel & AMD CPUs Queued Ahead Of Linux 6.11

([Linux Kernel] 5 Hours Ago AES-GCM)


The patches recently covered on Phoronix for [1]up to 162% faster AES-GCM encryption/decryption with modern Intel and AMD processors is now queued for introduction in the upcoming Linux 6.11 cycle!

Eric Biggers of Google has been working on some big performance improvements. After recently working on [2]much faster AES-XTS performance for modern Intel and AMD CPUs that was merged for Linux 6.10, he turned his attention to enhancing the AES Galois/Counter Mode performance.

This work is focused on VAES and AVX-512/AVX10 implementations of AES-GCM for up to 162% better performance. In addition to the new VAES and AVX-512/AVX10 optimized implementation, the AES-NI optimized AES-GCM has been rewritten. The big performance gains showed by Biggers are:

Very nice improvements for both encryption and decryption speeds.

The news today is the work has been queued into [3]cryptodev . With it now hitting the crypto subsystem's development tree, it should be submitted for the upcoming Linux 6.11 merge window in July.

The justifications for drug testing are part of the presently fashionable
debate concerning restoring America's "competitiveness." Drugs, it has been
revealed, are responsible for rampant absenteeism, reduced output, and poor
quality work. But is drug testing in fact rationally related to the
resurrection of competitiveness? Will charging the atmosphere of the
workplace with the fear of excretory betrayal honestly spur productivity?
Much noise has been made about rehabilitating the worker using drugs, but
to date the vast majority of programs end with the simple firing or the not
hiring of the abuser. This practice may exacerbate, not alleviate, the
nation's productivity problem. If economic rehabilitation is the ultimate
goal of drug testing, then criteria abandoning the rehabilitation of the
drug-using worker is the purest of hypocrisy and the worst of rationalization.
