This can be done by editing the $ARTIFACTORY_HOME/etc/artifactory.system.properties file and adding/changing the following parameters and their values.
The values above are the defaults (notice that the units are seconds).
The first value is the quiet period of the job itself. The second is the amount of time (quiet period) to wait per file deployment. So, in this example only after 60 seconds with no deployments will the calculation be marked and on the next job cycle (also up to 60 seconds in this case), the marked calculation will start.
