And then ./configure takes 19 seconds, and that's fully single-threaded, I believe? And... I'm guessing there's no way to get that to be multi-threaded?
You'd either have to rework Autoconf to make it multiprocess (difficult) or split configure.ac into pieces and run several './configure' pieces in parallel (this might be doable but would still be tricky).
00:01:17 INFO Scraping files for loaddefs.el... [...] 00:01:54 INFO Scraping files for loaddefs.el...done Which is single-threaded and takes a whopping 37 seconds! Could that possibly be parallelised in some way? Probably be tricky...
Yes. But this is probably the lowest-hanging fruit.
