Performance Discrepancy Between Non-Prod and Prod Power BI Gateway Refreshes

Hi Anonymous ,
Thank you for reaching out to the Microsoft fabric community forum. I appreciate the steps you've already taken to isolate the issue.

As jaineshp mentioned, check the load and version on both gateways, review logs for issues, and use diagnostic tools to spot bottlenecks. Also, test network latency and confirm if Premium capacity limits could be affecting refresh performance.

To assist further, Microsoft provides guidance on monitoring and optimizing on-premises data gateway performance, which you can refer to here: https://learn.microsoft.com/en-us/data-integration/gateway/service-gateway-performance These resources can help you interpret the diagnostics and understand underlying issues.

As lbendlin correctly mentioned, this forum is helpful for general support, but for a deeper investigation involving gateway logs or performance issues, it's better to contact Microsoft Support directly by raising a support ticket.

Hope this helps. Please reach out for further assistance.

Thank you.
