Hi back,
Ok, the 6 times slower thingy never happened again, so I’ll not take this in consideration.
But what’s sure is the following:
If I replace all $itemCustomFields['itemN'][0]
thingy by get_field('itemN', $id)
, the page loading is about max 30% slower.
So as you said before, get_post_meta($id) is indeed faster, but dealing with the returned data is way less easier then when using get_field.
So I’ll decide depending the need.
Sadly for the get_num_queries, I cannot see any difference since I’m calling my portfolio with Ajax. (or can I?)
