Does Substrate VM have cross-platform support for major operating systems (i.e. for Linux, Windows, MacOS)? If so, can a binary compiled on MacOS run on Windows, and vice versa?

Yes, that is the long term goal.

Project Metropolis is about rewriting OpenJDK C++ parts in Java, so SubstrateVM needs to support all major OpenJDK targets.

Doesn't (compiled) java run slower than c++ though?

[pjmlp]

Not necessarily.

It depends on the application, how it is written, the compiler and optimizer being used.
