Yes, non-native QEMU usually isn't any good for benchmarking the
architecture-optimized code, due to the instructions it uses having to be
emulated. Just to give another random example, in (non-native) QEMU the RISC-V
CRC code is much slower than the generic CRC code. But when run on an actual
RISC-V processor it's much faster.
