I have in a form 3 list lookups and besides I am using autocompleteplugin.js (http://words.usask.ca/sharepointsig/2013/10/25/replacing-a-drop-down-list-in-nintex-forms-with-an-autocompleting-textbox-using-jquery/). The problem is, that the loading time of the 3 list lookups is quite long. The form loads in 15-30 seconds.
None of the above affects the visibility of the control.
Does anybody succeeded to optimize performance by delaying the load of form controls?
