Also the rest of the equipment suggests that the build time should be reduced significantly. But build time did not change at all on the new laptop: [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: […]
