With this, my ARM64 test machine runs the benchmark `openssl speed -evp aes-256-gcm` nearly 20x faster going from 100 MB/sec to 2000 MB/sec It also improves sha256 from 300 MB/sec to 1800 MB/sec This fix has been accepted but not yet merged upstream: https://github.com/openssl/openssl/pull/17082 PR: 259937 Reviewed by: manu, imp MFC after: immediate Relnotes: yes Fixes: 88e852c0b5c872b1a ("OpenSSL: Merge OpenSSL 1.1.1j") Sponsored by: Ampere Computing LLC Sponsored by: Klara Inc.
