For the record, those are the lib sizes on Windows x86_64, VS2019 (LOW and SIZE uses currently the same opt flag, so same sizes) 204K /windows_x86_64/jdk-opt/images/jdk/bin/splashscreen.dll 1.4M /windows_x86_64/jdk-opt/images/jdk/bin/splashscreen.dll.pdb 352K /windows_x86_64/jdk-opt/images/jdk/bin/splashscreen.dll.stripped.pdb ------------- PR Comment: https://git.openjdk.org/jdk/pull/23493#issuecomment-2639948726
