I am able to read and write over 100MB/s from my softraid volume... I just backed up my home folder to my NAS and was able to hit gigabit line speed with CPU usage remaining low. I'm able to do this on my i7 3770 system and my Ryzen 2600x system.

They in his usual style... I understand, thanks for reply. Expecting better IO results only.

I think you are grasping at straws.
Re: Modern CPUs AES-NI enabling system wide
Thank you for answers. As I understand you right amd64 kernel supports AES-NI for ipsec, softraid, and LibreSSL only. Right? Just wonder, how to check softraid discipline exactly utilizes AES-NI instruction set on amd64 machine? Softraid created bioctl -r 8192 (for test purposes) works relatively slow ~10~12Mb/s on AES-NI enabled machines. Tested for Intel and AMD CPUs. cp command utilizes about 22% of CPU usage while copying.

The userland can still use AES-NI on i386; specifically, LibreSSL does. Of course all CPUs that support AES-NI can also run amd64. -- Christian "naddy" Weisgerber na...@mips.inka.de

You do need to pick suitable ciphers though. And it is only supported on OpenBSD/amd64 not OpenBSD/i386.

Modern CPUs AES-NI enabling system wide
How to enable AES-NI AES system wide hardware acceleration support for crypto disciplines like LibreSSL, softraid0 crypto etc?
