i have a fieldcollection field in a entity form type with FieldCollection Table display, and its set to unlimited value. In this field collection there are 5 fields. After some research I found that after insert 20/30 items, field collection slows down considerably. Infact, in my entityform, after 40 items of fieldcollection, increases the data loading time.
I'm looking for an alternative to fieldcollection with the ability to display the field in table such as field collection table.
can you help me?
