  22 |test purpose  | To evaluate the IaaS compute capability with regards to      |
  23 |              | memory utilization.This test case should be run in parallel  |
  24 |              | to other Yardstick test cases and not run as a stand-alone   |
  25 |              | test case.                                                   |
  26 |              | Measure the memory usage statistics including used memory,   |
  27 |              | free memory, buffer, cache and shared memory.                |
  28 |              | Both average and maximun values are obtained.                |
  29 |              | The purpose is also to be able to spot trends.               |
  30 |              | Test results, graphs and similar shall be stored for         |
  31 |              | comparison reasons and product evolution understanding       |
  32 |              | between different OPNFV versions and/or configurations.      |

  45 |              | operating system.                                            |
