Double the threads plus some improvements on single-thread execution, 2 minutes sounds right. > So getting down to 1 minute is probably feasible. 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. > But convincing somebody to buy a CI server like that will probably > remain a beautiful dream. Yeah, only in dreams I could have enough spare money to donate a 64-core machine to the FSF ;-)
