If it's of any value to anyone, perhaps as an indication of hardware/environment implementation, I get identical numbers (<1% difference) on Oracle's Ampere Altra servers with OpenSSL 1.1.1n on Debian 11.


Due to a peculiar design issue, Neoverse N1 underperforms when using RSA. It doesn't affect other use cases and is fixed on newer Arm cores.
