I don't know if it is true or not. However, I think we can give the VM more RAM, which can help with speed. Also, in our recent "raw compute" benchmarks, ARM was 5 times slower uniformly than an Intel core i7 laptop at the same clock speed... so if qemu is "20% of native speed", then it would be about the same, maybe. Also, the disk in the VM could be faster than the disk in a typical ARM box.
