Hi Philip, Tnx for your tip. But I made 100% sure NOT to include the .git directory. And still I get a the difference between 2 tar-files. One made from the source before committing and pushing, and the second tar, made from the same source after cloneing and checking-out. I would expect them to be the same size (apart from small differences due to .gitignore etc). But an 20% increase is too much !
