    That's pretty significant, because if you can disable breakpoints,
    then you can disable perf. Together they make quite a chunk.

    breakpoints + perf:

    text data bss dec hex filename
    1567422 348628 511680 2427730 250b52 vmlinux


    none:

    text data bss dec hex filename
    1478031 333220 508256 2319507 236493 vmlinux
