Over the years, I’ve learned to ignore emails from this sender. That said, I’d still like to point out that I suspect that even if you don’t build in tmpfs, building a kernel package particularly quickly with (so many jobs in) "8GB of RAM" is unlikely to be possible. When I last built my own kernels a few years ago, significantly more RAM was already required just to make building in tmpfs possible at all. How long it takes to build a kernel in a VM naturally depends on the VM and the kernel configuration, but generally, the number of jobs and the amount of RAM provided must be in balance, even if you’re not building in tmpfs. I think the days when you could get by with 8 GiB of RAM are over. To speed up the build process in a VM, I would streamline the kernel configuration. A default Arch Linux kernel configuration will likely support exotic hardware that would never be of any significance in a virtual machine.
