-| Compute Concurrency                           | 5 concurrent audiences                | Segment computes five new audiences or computed traits at a time. Once the limit is reached, Segment queues additional audience computations until one of the five audiences finishes computing.                                                                                                                                                                               |

Once the limit is reached, Segment queues additional computations until one of the five finishes computing.                                                                                                                                                                               |
+| Edit Concurrency                           | 2 concurrent audiences or computed traits               | You can edit two concurrent audiences or computed traits at a time. Once the limit is reached, Segment queues and locks additional computations until one of the two finishes computing.                                                                                                                                                                               |
 | Compute Throughput                            | 10000 computations per second         | Computations include any Track or Identify call that triggers an audience or computed trait re-computation. Once the limit is reached, Segment may slow audience processing.                                                                                                                                                                                                   |
 | Events Lookback History                       | 3 years                               | The period of time for which Segment stores audience and computed traits computation events.                                                                                                                                                                                                                                                                                   |
 | Real-time to batch destination sync frequency | 2-3 hours                             | The frequency with which Segment syncs real-time audiences to batch destinations.                                                                                                                                                                                                                                                                                              |
