-Beyond the capacity of the purchased throughput units, ingress is throttled and Event Hubs throws a [ServerBusyException](/dotnet/api/microsoft.azure.eventhubs.serverbusyexception). Egress doesn't produce throttling exceptions, but is still limited to the capacity of the purchased throughput units. If you receive publishing rate exceptions or are expecting to see higher egress, be sure to check how many throughput units you have purchased for the namespace. You can manage throughput units on the **Scale** page of the namespaces in the [Azure portal](https://portal.azure.com). You can also manage throughput units programmatically using the [Event Hubs APIs](./event-hubs-samples.md).

 Throughput units are prepurchased and are billed per hour. Once purchased, throughput units are billed for a minimum of one hour. Up to 40 throughput units can be purchased for an Event Hubs namespace and are shared across all event hubs in that namespace.
