 ### Optimize performance when using local NVMe
 
-Depending on your workload’s performance requirements, you can choose from three different performance tiers: **Basic**, **Standard**, and **Advanced**. Your selection will impact the number of vCPUs that Azure Container Storage components consume in the nodes where it's installed. Standard is the default configuration if you don't update the performance tier.

 These three tiers offer a different range of IOPS. The following table contains guidance on what you could expect with each of these tiers. We used [FIO](https://github.com/axboe/fio), a popular benchmarking tool, to achieve these numbers with the following configuration:
