Hi Elliot,
I hope you don’t mind double posting but I don’t want mix questions with my findings
The acf.conditional_logic.change function has a line:
$.each(this.items, function( k, item ){
which loops through all items with conditional logic. In my case with 9 rows this.items has 255 elements and loop takes 10 seconds to complete.
Each extra row add another 10-40 items depending on the complexity of the nested repeater fields.
In the embedded code for each field you put them all in one bag:
acf.conditional_logic.items.push({
This ultimately kills the performance of conditional logic fields. I suggest you rewrite the code so the repeater field holds separate conditional_logic object with its own children only rather than refer to the global object with all items.
I’ll keep digging what is causing other slowdowns.
