| """Script to compare ChromeOS benchmarks |
| |
| Inputs: |
| <perflab-output directory 1 - baseline> |
| <perflab-output directory 2 - results> |
| --csv - comma separated results |
| |
| This script doesn't really know much about benchmarks. It simply looks for |
| similarly names directories and a results.txt file, and compares |
| the results and presents it, along with a geometric mean. |
