Other workloads with noticeable performance hits (at least relevant to my day to day work): * Code compilation - Linux kernel compilation takes ~15% longer with any of the mitigations on. LLVM and Node compilation are less substantial for kernel only, or safe RET microcode fix, but still ~15% longer for the IBPD mitigation. Though the Linux kernel gap seems much smaller (~7%) when tested on desktop ryzen (zen 4) instead of EPYC (zen 3) * Numpy benchmark - at least ~10% loss with mitigations (on EPYC) * nginx - at least ~15% with loss with mitigations (on EPYC) Most other impacts limited to less than 5% (if any).
