- [Event Hubs Premium](./event-hubs-premium-overview.md) provides superior performance and better isolation within a managed multitenant PaaS environment. The resources in a Premium tier are isolated at the CPU and memory level so that each tenant workload runs in isolation. This resource container is called a *Processing Unit*(PU). You can purchase 1, 2, 4, 8 or 16 processing Units for each Event Hubs Premium namespace.

 How much you can ingest and stream with a processing unit depends on various factors such as your producers, consumers, the rate at which you're ingesting and processing, and much more. 
 
-For example, Event Hubs Premium namespace with 1 PU and 1 event hub(100 partitions) can approximately offer core capacity of ~5-10 MB/s ingress and 10-20 MB/s egress for both AMQP or Kafka workloads.
