 ## Sizing and estimation: provisioned deployments
 
-Determining the right amount of provisioned throughput, or PTUs, you require for your workload is an essential step to optimizing performance and cost. If you are not familiar with the different approaches available to estimate system level throughput, review the system level throughput estimation recommendations in our [performance and latency documentation](./latency.md). This section describes how to use the Azure OpenAI capacity planning tooling to estimate the number of PTUs required to support a given workload.
