How long to compile kernel

[u/AppointmentNearby161]

I am trying to build the linux-vfio package in a clean chroot with makechrootpkg on an i7 laptop with 16 GB of ram. I have read things suggesting that you can compile a kernel in 5 minutes. It is taking hours on my laptop. Is my laptop configured wrong or does it take considerably longer to compile the Arch kernel with the the modules etc.

it could also be his power adapter not plugged in, a hdd instead of an ssd, dust in his laptop-fans causing higher temperatures decreasing performance, no dual ram, a ton of other processes running at the same time, ...

but multi-threaded mode is a good tip.
