I’ve noticed very weird thing – my client put 105 images in gallery field. I’ve tried to get them using ‘get_field’ function. It works but it takes about 4-5 second on client’s server. I’m talking only about execution time of get_field function.
So, here are results from my localhost, gallery field with 105 images:
1) get_field – 1.0430738925934s
2) get_post_meta – 0.00030398368835449s
