The production DuraCloud Vault bridge application during a period of high activity in Jan-Mar 2018 landed on these settings, which provided the preferred load average:
| CPU Cores | 24 |
|---|---|
| jobTaskExecutor size (maxPoolSize and corePoolSize) |
...
| 7 | |
| threads-per-job |
...
| 5 |
The total potential threads with these settings is (7 * 5) = 35.
This was with a setting of 24 CPU cores on the bridge VM. This suggests that a ratio of potential threads to CPU cores of (35 / 24) = 1.45 is about right.
Attempting to achieve the same ratio for a machine with 8 CPU cores, might suggest settings like:
| CPU Cores | 8 |
|---|---|
| jobTaskExecutor size (maxPoolSize and corePoolSize) |
...
| 4 | |
| threads-per-job |
...
| 3 |
Total potential threads (4 * 3) = 12. Ratio of potential threads to CPU cores = 1.5.
