Power BI report Server slow

    Hi denisciola ,

    If your server is dedicated to Power BI Report Server, you can enhance performance by increasing the TotalMemoryLimit in the msmdsrv.ini file to 90–95%. This change enables the Analysis Services engine to use more of the available memory, thereby improving report efficiency.

    Recommended

    1. TotalMemoryLimit - 90–95%
    2. LowMemoryLimit - Typically 60–70%, adjustable based on workload

    After implementing these changes, it's essential to monitor system memory usage to ensure stable performance. Even on a dedicated server, tracking key performance counters will help verify that the OS retains sufficient resources.

    you're saying that the SSAS service consumes 100% of the memory.

    IMHO this could mean:

    - report are too expensive

    - memory is not enough for your workloads

    - or both

     

    how much memory has this server?

     

    most of the time bad performances come from bad report/model design. 

    for example:
    - useless data imported (this amount of data will reside in RAM)

    - wrong data types

    - bad DAX patterns 

    - ...

     

    have you alredy check the reports with devs?
