Best Practices to Improve Slow Loading Times in Data Tables

Hey guys, Getting some issues with slow loading times and wondering if there are some best practices to help: . Loading columns, eg lookup other table, seems to be running a lot slower than it used to. . Making UI changes like limiting row numbers used to happen immediately, but now won't propagate unless i refresh the page. I have tried this across multiple Clay logins and across multiple browsers and seems to persist. Any pointers from the team? Cheers.
