The most interesting bit about this article for me is the "transition time" to get the power needed use AVX-256 or AVX-512 which is present on Intel, but not AMD zen4/zen5. It explains some behavior that I saw years ago when implementing kTLS on FreeBSD, and validates our design of having per-core kTLS crypto worker threads, rather than doing the crypto in the context of sosend() or sendfile's tcp_usr_ready().
