In your case, the test with OpenSSL 1.1.1k without '-evp' stands (far) out from your other score in a positive way. In my case, it is the same combo that stands out in a negative way. https://openwrt.org/docs/techref/hardware/cryptographic.hardware.accelerators#finding_out_what_s_available_in_the_kernel is the only page I found wrt /proc/crypto and I do indeed have several 'skcipher' and 'shash' nodes with prio >= 300. That article also speaks about /dev/crypto, but I don't have that. So there's a reasonable chance I indeed do have HW accelerated crypto, but it doesn't seem to be near '10x' speed improvements. Thermal issues may also play a role. I noticed that if I did a test after letting the device idle for a while, so it can cool off (?), did result in higher scores. The Rock64 tends to get (quite) hot pretty quickly and that _may_ mean it throttles back quickly. I haven't done any measuring, so I may be completely off on this. I'm pretty sure the RPi (4) has had more man-power devoted to this issue. Cheers, Diederik
