OK, I just put on another git repo, which is the simpley helloworld in D, and it generates 849KB for print a single line! https://github.com/dangbinghoo/hello_world_d so, maybe there's something wrong with D compiling? thanks! OK, talked in Discord. answer is clear: 1. D runtime is about 400KB on amd64 stripped. 2. phobos is set of big templates, writeln is expensive. betterC print a helloworld only costs 6.3KB stripped. thanks!
