Really we wanted to improve Linux side of things, that is where we are scratching the runner space limits. I have not looked at Windows side at all; so please experiment and see how bad is it? I also have this improvement for Linux/MacOS: https://github.com/openjdk/jdk/pull/29056 -- again, does not help Windows, since I cannot find a useful/relevant MSVC toggle there. ------------- PR Comment: https://git.openjdk.org/jdk/pull/29030#issuecomment-3713766995
