1) For disk I/O tests
< 40 MB/s is below average
40 - 80 MB/s is about average
80 MB/s -120 MB/s is very nice
120 MB/s + is outstanding
2) For Unixbench CPU benchmarks (single CPU)
< 150 is poor
150-300 is ok for a budget VM
300-400 is average
400-500 is very good
500+ is outstanding for a budget VM
