Hello!
I have > 200 fields in webform. In views I use only 10 of them to show in view. There are only 5 submissions in my test site.
First opening of view takes about 1 minute.
I need to use filters for users. But filtering or sorting takes some minutes to be finished.
Maybe problem is that data isn't indexed. But how to do it if mysql table with data is read only and structure can't be changed?
