Using ThinLTO manages to optimize binaries quite significantly. The exact amount varies a lot by program but it's about 10-15% usually. Don't remove non-ThinLTO support yet. It would not surprise me if this triggered some unintended side effect. Eventually, non-ThinLTO support should be removed though.
