Premium Event Hub performance issue

Question

I have a premium Event hub namespace with 2 PUs having 15 event hubs;

I find the document says Event Hubs Premium namespace with one PU and one 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.

And my testing case was 200 messages/sec with each message being 60 Kb long, I can add many threads.but how to increase the ingress and egress ? The single event hub only have a maximum of 100 partitions?

My question is, how to increase the partition to 150 ?

Hello @李想

welcome to this moderated Azure community forum.

according to the documentation, You need to scale up the number of units:

Number of partitions per event hub (Premium): 100 per event hub, but there's a limit of 200 per PU at the namespace level. For example, if a namespace is assigned 2 PUs, the limit for total number of partitions in all event hubs in the namespace is 2 * 200 = 400.

For premium, there is no throughput limitation:

Throughput per unit (Premium): No limits per PU (Depends on various factors such as resource allocation, number of partitions, storage, and so on.)
