6.19.1.4. Software configuration on servers with rally role¶
On this server should be installed Rally. How to do it you can find in Rally installation documentation
| Software | Version |
|---|---|
| Rally | 0.4.0 |
| Ubuntu | Ubuntu 14.04.3 LTS |
6.19.2. Test results¶
6.19.2.1. Create Neutron networks¶
In this test case Rally creates Neutron networks at constant rate. Achieved maximum rate: 5 RPS.
| Response Times (sec) | ||||||||
| Action | Min (sec) | Median (sec) | 90%ile (sec) | 95%ile (sec) | Max (sec) | Avg (sec) | Success | Count |

6.19.2.2. Create Neutron network with port¶
In this test case Rally creates Neutron network with one Neutron port at constant rate. The summary duration time is measured and dependency on number of requests per second is shown.
| RPS | Min (sec) | Median (sec) | Max (sec) | Avg (sec) |
|---|---|---|---|---|
| 5 | 0.505 | 0.658 | 4.712 | 0.795 |
| 10 | 0.468 | 0.635 | 2.789 | 0.712 |

6.19.2.3. Create and list Neutron ports¶
In this test case Rally creates Neutron network with 20 ports and lists them. Operations are requested at constant rate. Achieved maximum rate: 0.1 RPS.
| Response Times (sec) | ||||||||
| Action | Min (sec) | Median (sec) | 90%ile (sec) | 95%ile (sec) | Max (sec) | Avg (sec) | Success | Count |

6.19.2.4. Create Cinder volumes¶
The following chart and table show how operation duration depends on number of requests per second. The median grows, at 8 RPS one of request falls out of 1 minute.
| RPS | Min (sec) | Median (sec) | Max (sec) | Avg (sec) |
|---|---|---|---|---|
| 1 | 2.462 | 2.578 | 3.158 | 2.607 |
| 2 | 2.474 | 2.616 | 3.029 | 2.644 |

6.19.2.5. Boot Nova Server¶
The following chart and table show how operation duration depends on number of requests per second. Success rate falls beyond 100% as some of operations take longer than the timeout limit.
| RPS | Min (sec) | Median (sec) | Max (sec) | Avg (sec) | Success (%) |
|---|---|---|---|---|---|
| 1.5 | 12.234 | 29.197 | 118.353 | 34.074 | 100 |
| 1.7 | 12.626 | 34.993 | 182.083 | 48.736 | 98.4 |
| 2 | 13.426 | 37.698 | 298.564 | 50.021 | 70 |
