Double the threads plus some improvements on single-thread execution,
2 minutes sounds right.

You will need many threads and a fast CPU for that :-) More so as new
barriers are made apparent as you increase the threads. Plus the machine
will often execute more than one build on parallel, or queue them.

Yeah, only in dreams I could have enough spare money to donate a 64-core
machine to the FSF ;-)
