As someone who remembers 2 hour kernel + module builds in the 90s, this is
really hard to wrap my head around. Sure, even my desktop machine in the last
couple of years has been able to get that down well under 10 minutes, this is
just mind boggling to me.
No silly tricks here, this is built using the default ("defconfig") - but I’m
sure the Intel Optane 900p NVMe drives certainly don’t hurt. Especially because
the author believes it is I/O bound.
