DAX Optimizer performs a static analysis of DAX measures in a Power BI or Analysis Services model. It produces a prioritized list of potential bottlenecks caused by DAX code and suggests possible solutions using sample DAX code.
DAX Optimizer prevents performance issues by enabling DAX authors to optimize the code before creating reports. In the case of existing slow reports, the suggestions provided by DAX Optimizer are likely to solve the performance issues experienced.
DAX Optimizer is designed for both individual model authors and teams of developers who contribute to a shared data model definition. This means that the software provides you with the possibility to choose between having a license for your own or one shared with a group of contributors, for collaborative purposes.

Before learning more about how to use DAX Optimizer, you can learn the following:
Cloud storage and processing
DAX Optimizer is implemented by using Microsoft Azure services. The VPAX files are stored in separate Azure storage accounts: every user and every workspace has a separate Azure storage. This way, the data of different customers do not share the same Azure storage account.
When users choose the Region for an account or a workspace, they select the Azure region for the storage account and all the services used to perform the analysis. This collocation of storage and services improves service performances and guarantees that customer data never leaves the chosen region.
Plans and licensing
You can choose among different types of plans and licensing.
Each plan provides a certain number of runs you can perform and a certain number of models that DAX Optimizer can analyze. This means that if you need to analyze more than one model, you can choose the license accordingly.
