On the dangers of Intel's frequency scaling

The performance of the cipher ChaCha20-Poly1305 does not scale well when using Intel's AVX-512 instruction set, which consumes a lot of power and leads to dynamic frequency scaling. This results in reduced CPU frequencies when executing AVX-512 instructions, impacting server performance negatively. While the issue might be resolved with future generations of CPUs, users are advised to disable AVX-512 execution on their servers or desktops if they do not require it for specific high-performance tasks.
