| cyclictest -t 5 -p 80 -n -q -l 10 |
| |
| runs a test with 5 threads, stops after 10 loops and outputs: |
| |
| T: 0 ( 2215) P:80 I: 1000 C: 10 Min: 31 Act: 33 Avg: 33 Max: 43 |
| T: 1 ( 2216) P:79 I: 1500 C: 10 Min: 22 Act: 22 Avg: 36 Max: 61 |
| T: 2 ( 2217) P:78 I: 2000 C: 10 Min: 27 Act: 33 Avg: 36 Max: 50 |
| T: 3 ( 2218) P:77 I: 2500 C: 10 Min: 23 Act: 37 Avg: 38 Max: 59 |
| T: 4 ( 2219) P:76 I: 3000 C: 10 Min: 26 Act: 48 Avg: 36 Max: 48 |

| All numbers in micro seconds. You get the minimium, maximum and average latency for each thread. |
| |
| I use this for automated regression testing. |
| |
| The -v option outputs: |
| |
| 0: 0: 0 |
| 0: 1: 45 |
| 0: 2: 41 |
| 0: 3: 31 |
| 0: 4: 31 |
| 0: 5: 34 |
| 1: 0: 0 |
| 1: 1: 29 |
| 1: 2: 33 |
| 1: 3: 33 |
| ... |
| where the first column is the thread, the second column is the loop |
| counter and the third is the latency value for this step. You can use |
| this for your own statistics or for latency distribution plots. |
