That is "10 times faster", not "10 times slower".
More and faster CPU cores and RAM, and fast low-latency secondary
storage will help a bit. Just now, autogen / configure / make
took 8.4s / 41.7s / 3min 31.0s respectively in MSYS2 on Windows,
and about 2s / 16s / 2m 46s in an Ubuntu VM.
Experiment with larger values for -j (the builds above were at -j24
on an 8-thread machine) as there's plenty of stuff to be going on with
that doesn't need a CPU core.
Windows is ridiculously slow to start a new process. That seems to
account for a big proportion of the time it takes to run the configure
script. Disable the App Compat engine (from orbit, it's the only
way to be sure).
