Generically, any query that returns more than 10K rows results in a browser slowdown on display/adjustment. I’m wondering if that limit is related to # of columns, column complexity, or something else, and whether it can be resolved or it’s a limit of the javascript used for the front-end?

Thanks!

This is the cause, but 10k should work ok unless you have many, many columns. Redash works best with < ~20mb of data.

So I have experienced problems with 300KB of data, <10K rows, 5 columns.

10K rows is really not much data to manipulate. It seems like there is an underlying issue with the javascript.
