- Field Detail
  - corePoolSize
```
protected int corePoolSize
```
    The minimal number of threads that are kept alive in the threadpool for job execution
  - maxPoolSize
```
protected int maxPoolSize
```

  - keepAliveTime
```
protected long keepAliveTime
```
    The time (in milliseconds) a thread used for job execution must be kept alive before it is destroyed. Default setting is 0. Having a non-default setting of 0 takes resources, but in the case of many job executions it avoids creating new threads all the time.
