Could you also let me know which exact version of Baserow you have installed? You can find the version by doing cat /baserow/baserow/README.md at the bottom.
Also the table you are inserting into here, could you let me know how many different views this table has? And on average how many filters and sorts each one of these views for this single table has?
For those interested the model caching changes on our develop branch due to be released shortly were able to help out with the slowdown ozz was having.
The first one was to delete and create a new distribution table. Because the former one has a lot of history with a lot of tables linked and removed and other recreated.
I got the feeling that the history management could be improve and a lot of table should be really erased from the database.
