The Linux 6.19 kernel delivers up to 74% faster AES-GCM cryptographic performance for AMD Zen 3 processors. This improvement stems from optimizations in the kernel's crypto subsystem. Phoronix reports these gains based on hardware benchmarks.
Phoronix has highlighted significant enhancements in AES-GCM crypto performance with the Linux 6.19 kernel, particularly for AMD Zen 3-based systems. Benchmarks show improvements of up to approximately 74% in processing speeds for this widely used encryption algorithm.
AES-GCM, or Advanced Encryption Standard with Galois/Counter Mode, is a common cryptographic primitive employed in secure communications and data protection. The performance uplift is attributed to better utilization of AVX2 instructions on AMD Zen 3 architectures, as integrated into the kernel's crypto code.
This update aligns with ongoing efforts in the Linux kernel to optimize hardware-specific features for modern CPUs. Phoronix, known for its Linux hardware reviews and benchmarks, tested these changes using tools like the Phoronix Test Suite on Ubuntu systems.
The keywords associated with the report include Linux hardware benchmarks, server benchmarks, desktop Linux performance, and open-source graphics, underscoring the broad relevance to Linux users and developers. No specific release timeline beyond Linux 6.19 is mentioned, but such kernel merges typically appear in the mainline tree ahead of stable releases.
These optimizations could benefit applications involving encryption, such as VPNs, secure file systems, and web servers running on AMD hardware.
