The Librem 14 running Pure OS Byzantium off a USB stick did a normal release build of ARSE 0.11.0 in 1m30s. I need to build it in Qubes OS again and make note of the time for a better comparison because I did add two new dependencies between 0.9.0 and 0.11.0.
Lots to like about this machine.
1m34s from my projects qube for a release build of ARSE 0.11.0. Pretty impressed by how close the VM performance is to the live distro performance.
