+|test purpose  | To evaluate the IaaS compute performance with regards to     |
+|              | memory bandwidth.                                            |
+|              | Measure the maximum possible cache and memory performance    |
+|              | while reading and writing certain blocks of data (starting   |
+|              | from 1Kb and further in power of 2) continuously through ALU |
+|              | and FPU respectively.                                        |
+|              | Measure different aspects of memory performance via synthetic|
+|              | simulations. Each simulation consists of four performances   |
+|              | (Copy, Scale, Add, Triad).                                   |
+|              | Test results, graphs and similar shall be stored for         |
+|              | comparison reasons and product evolution understanding       |
+|              | between different OPNFV versions and/or configurations.      |

+|              | * SLA (optional): 7000 (MBps) min_bandwidth: The minimum     |
+|              |   amount of memory bandwidth that is accepted.               |
+|              | * type_id: 1 - runs a specified benchmark (by an ID number): |

+|              |     3 -- INTmem                     6 -- FLOATmem            |
+|              | * block_size: 64 Megabytes - the maximum block size per array|
+|              | * load: 32 Gigabytes - the amount of data load per pass      |
+|              | * iterations: 5 - test is run 5   times iteratively.         |
+|              | * interval: 1 - there is 1 second delay between each         |

+|              | RAMspeed is a free open source command line utility to       |
+|              | measure cache and memory performance of computer systems.    |
+|              | RAMspeed is not always part of a Linux distribution, hence it|
+|              | needs to be installed in the test image.                     |
