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
