Some more information.
I am talking about 14 columns here and 10,000.
I did testing with 3 columns and 10,000 rows. It is still the same
behaviour.
When I tested with 14 columns and 500 rows, it is doing much better.
I don't have any boolean renders/images here. I have couple of float
columns. If string gives better performance, I can convert them to string if
I know how to do that.
Thanks.
