Raspberry Pi 3/aarch64 headless LAMP+Openvpn

[graysky]

I read the disclaimer regarding vendor extension, libs, etc. as well as a few posts in the forums about the aarch64 on the RPi3. Is anyone using this kernel/arch for a headless LAMP or OpenVPN box? I'd like to run a few LXCs (one for openvpn and another for a LAMP/nextcloud) on aarch64. Any issues experienced by some or foreseeable? Thanks for sharing.

Got the lxc and openvpn configured and running but there seems to be a sluggish feeling on the CLI. As well, I am getting some coredumps in dmesg:
