I am aware of that, but there have been NEON AES optimisations floating around, e.g.: https://www.linaro.org/blog/accelerated-aes-for-the-arm64-linux-kernel/
I guess what I'm asking is if EL8 aarch64 ships with any such thing enabled, and any other tweaks I could try to squeeze more ssh speed out of it. I'm finding that piping data over aes-128-cbc (which seems to be the fastest implemented cipher) over gigabit ethernet tops out at about 30MB/s per CPU core, with each ssh session being limited to this (even though I can run 8 sessions in parallel at that speed).

X-Gene cpu present in your machine lacks AES instructions support. _______________________________________________ Arm-dev mailing list Arm-dev@centos.org https://lists.centos.org/mailman/listinfo/arm-dev
