What says "file" about the files in /usr/src/linux* on your side?
Does stripping remove the debug information? |

@Tony0945 -- Some people care about size in /usr/src because they (like me) keep multiple kernel sources and excessively large files take away from their comfortable elbow room. On most, but not all, systems, I have plenty of elbow room. One thing about Gentoo, it takes plenty of elbow room to maintain.

So perhaps little more difference in size on your side is visible in the "modules department" ( /lib/modules/ or similiar) ??
My kernel has no modules. |
