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!
We never found a solution to the issue and the support from Tableau was horrible... We're hesitant to upgrade again for obvious reasons, but then again it's also very likely we will change BI Software, because Tableau has become just too buggy
