Experiencing Extreme Slowness with Decomposition Tree when Presented in PowerPoint

Hi, pparker9834 

Happy answering your questions. Here's why inserting a report in PowerPoint is slow when using the Decomposition Tree:

1. The decomposition tree uses a large dataset or is computationally complex.
2. Network latency can impact report performance by increasing the time it takes for a request to reach the Power BI service, as well as the time it takes to deliver a response. Tenants in Power BI are assigned to specific regions. When a user in a tenant accesses the Power BI service, their requests are always routed to this region. When a request arrives at the Power BI service, the service may send additional requests (for example, to the underlying data source or data gateway) that are also affected by network latency.

3. The maximum number of levels of the decomposition tree is 50. The maximum number of data points that can be visualized at one time on a tree is 5000. When you have a lot of decomposition tree levels, it can lead to long response times.

You can optimize your reports for speed by following these steps:

1. Optimize your dataset. Check if your dataset can be further optimized.
2. Optimize visualizations. You can optimize your dashboard/Power BI reports based on your actual situation.

3. Optimize the environment. This section includes: Optimize the environment, capacity settings, gateway sizing, and network latency.

4. Adjust your decomposition tree, such as reducing the level of the decomposition tree
