Antoine Pitrou commented on ARROW-16794:
----------------------------------------
To come back to the timeout problem, though, the obvious solution is indeed to
bump the timeout.
However, it is quite worrying that pure C++ builds on CI are now nearing the
one hour build time. One thing specific to the MinGW builds is the fact that
they build in Release mode (probably because Debug builds on Windows are
complicated). One mitigation would be to override CFLAGS and CXXFLAGS to
disable most optimizations.
