A single match from the negotiator can be used to run several jobs. When
a job finishes, the schedd tries to send another job to that same machine.
If you want timings on when these extra jobs get sent to the executing
machine, you'll need to look at the logs on the submit machine (schedd,
shadow, and user logs).
