On a build box with 8GB RAM, building an ISO using tmpfs is *really*
faster: the IO subsystem stops being the bottleneck, which now is the
single CPU core speed (apart of mksquashfs, most of the build runs on
a single CPU)... and the build time decreases *a lot* (no handy benchmark
numbers, but I do remember my amazement when I switched to building in
tmpfs).
Once this step is done we can think of improving the CPU-bound build
time, but practical experience showed me it was a really great first
step to globally improve build time.

Could you please elaborate on this?
