It appears in my current environment \P2P_Dropdown::get_choices called from \P2P_Dropdown::render_dropdown may be causing ALL posts of the current list type (read 1000's) to be queried when the connected posts (< 10) are populated for the dropdown.
Also whilst only ID and title are required to populate the dropdown all meta data for all items is also loaded.
Highlighting here on the off-chance someone picks up on developing this plugin again.
