lscpu | grep aes
If the command returns nothing, sadly your CPU does not support hardware AES acceleration, or if you run your OS in a VM, then the VM operator likely did not set "host" as CPU model.
If however the command does output a list of flags, with aes highlighted in red (depends on SSH client), then you can safely add the following line to your nodes configuration file:
HardwareAccel 1
I don't think this is necessary to make it use AES. It would use that automatically. HardwareAccel is needed only to enable some external OpenSSL acceleration engines, such as the defunct "VIA Padlock".
