iercan opened a new issue, #31799: URL: https://github.com/apache/superset/issues/31799
### Bug description We are using superset 2.1.1. We wasn't able to upgrade it since this version because we were experiencing performance issues on some dashboards(slow reactions and sometimes crashes). After further investgations we have detected this is causing by pivot table migration. All problematic dashboards had some legacy pivot tables. I'm opening this issue aiming to help anyone experiencing same issue because we also have a workaround. **How to reproduce.** 1. Create a dashboard that has at least 4-5 legacy pivot table on version 2.1.1. (Our charts had 10000 row limit but I'm not sure this is relevant) 2. Migrate superset after any version bigger than 3.0.0 **Workaround** As a workaround we just save and overwrite these charts and problem has gone. ### Screenshots/recordings _No response_ ### Superset version master / latest-dev ### Python version 3.9 ### Node version 16 ### Browser Chrome ### Additional context _No response_ ### Checklist - [X] I have searched Superset docs and Slack and didn't find a solution to my problem. - [X] I have searched the GitHub issue tracker and didn't find a similar bug report. - [X] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section. -- This is an automated message from the Apache Git Service.
