"/feed");  $i = 0;  foreach($pagefeed['data'] $post) {     if ($post['type'] == 'video' || $post['type'] == 'link' || $post['type'] == 'photo') {          // open fb-update div         echo "<div class=\"fb-update\">";          // check if post type link         if ($post['type'] == 'link') {             echo '<a href="' . $post['link'] . '" target="_blank"><img class="imagem-feed" src="' . $post["picture"] . '"></a>';             $interno = "<p>" . $post['message'] . "</p><p><a href=\"" . $post['link'] .

using code, page slow (50 seconds load). tested thing optimize , don't improve. can me?

you making calls graph api inside loop, i.e every post, making additional calls. obviously, contributes towards 50 secs. best bet arrange code use batch requests. here documentation batching calls.

https://developers.facebook.com/docs/graph-api/making-multiple-requests/

note: can make upto 50 calls in 1 go using batch request.
