 ## Sizing and estimation: provisioned and global provisioned
 
-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 available. The tool provides you with an estimate of the required PTU to meet the needs of your workload.
