Even if extra bounds checking makes code 10% slower, which seems very unlikely, the benefit of the extra hardening would still be worth it. _FORTIFY_SOURCE=3 is going to make it harder to hack Fedora users, converting code execution vulnerabilities into denial of service vulnerabilities.
No, it doesn't. 3% maximum is acceptable in this case.
Me and all my friends use mitigations=off. A huge performance penalty
for the sake of potential vulnerabilities that still need to be able to
exploit.
