Hi Chris, thanks for the explanation and details of the minimal-vm . > My point here is that if you want small footprint, you can choose that, and > expect some performance hit as a result Unfortunately , the JDK native libs are always compiled with the default settings (mostly LOW, for a few HIGH(EST)) so I cannot choose much. The minimal vm is interesting but as it is, it is not really a good choice. Maybe we need better configure support to influence how the JDK libs are built. On the other hand , most JDK libs have optimization LOW set, that does not look like they care too much about best performance. ------------- PR Comment: https://git.openjdk.org/jdk/pull/23563#issuecomment-2677689127
