Hi everyone,
we recently upgraded our Tableau Server from 2023.3.12 to 2025.1.7 (Linux 64 Bit) on 3 nodes. What we have witnessed is that the loading times for viewing Worksheets / Dashboards has absolutely exploded (Simple dashboards regularly take 1-5 minutes to load which previously took 5 seconds to load). Nothing was changed to the infrastructure, the only change was the upgrade. The CPU usage is relatively low of the nodes, only when a worksheet / dashboard is viewed there's a huge spike in the hyperd process...
What we have tried so far:
- Resaving all data sources again + full refresh of all extracts
- Increasing VizQL server processes from 4 (in total) to 8 (hasn't really helped)
- Increasing the data file storage process so that all 3 nodes now have this service (we thought perhaps the exchange between the nodes might be reducing performance)
We are becoming increasingly desperate as to how to fix this, because the current state of this is not usable...
Please don't make any suggestions like "we should reduce the number of rows or we should optimise our data sources". This hasn't changed at all in comparison to the 2023.3 Version and with the use of 3 nodes the system should easily be able to handle the loading of simple worksheets.
Does anyone know what could be helpful? Thanks in advance!
Hey,
I have exact similar issue, I upgraded stage server to 2025.3.3 and faced rendering issue followed by session id err or just no response, THEN I upgraded stage to 2025.3.6 this version has also same issues no change. I have worked/working with Tableau on this which is mostly giving tsm logs, HAR logs & RMT logs. Something immense has changed with this version as the TDS communication is not working. I have disable enabled number of services on Tableau recommendations but had no luck. Either clone 2026 as is with 2024 or just copy paste your 2024 version and label it 2026. This issue is really getting on nerves so question is...
WHAT IS THE RESOLVE?
How can we look under the hood of whats changed? what services arent upto date>?
Tableau please get this game right.
