I had to uninstall objective C, though.
It complained about a dependency.

Version 9.1.0 seems to create slow executables. Version 8.3.0 was better (almost as 4.9.2)

I didn't know msys2 existed - I've been stuck on mingw-w64 with an outdated gcc version until now.

GCC 9.1.0 generates an executable of pretty much the same speed for me.

Me too. I use PGO, so I suspect that is why. Maybe it's not as good right out of the box.
The main thing that gets me excited about a new release is new language features and bug corrections.
