Facebook Graph API Slow for Larger Data Calls

This is what I am doing in PHP to get access to a bunch of group posts on Facebook. I'm then implementing a search function to search these posts.

        $url2 = 'https://graph.facebook.com/'. $group_id . '/feed' . '?limit=30&access_token=' . $_SESSION['access_token'] ;

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, "$url2");
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $json = curl_exec($ch);
        $data = json_decode($json, TRUE);

So I broke it down and just found that putting the graph url into my browser yields a slow response. Limit set to 30 is ok, but up it to 300 and it is slow, up it to 1,000 and it crawls.

I've looked into paging but I would like to grab a large amount of data so I can search it. Caching really wouldn't work because it still takes so long to load that initial data.

Is there anyway to speed this up or am I stuck at the limitation of the Facebook Graph API?

You could batch your requests so that you only set the curl once for the batched request, instead of looking through numerous curls http://developers.facebook.com/blog/post/2011/03/17/batch-requests-in-graph-api/

    $app_id = "YOUR_APP_ID";
    $app_secret = "YOUR_APP_SECRET"; 
    $my_url = "YOUR_URL";

    $code = $_REQUEST["code"];

    if(empty($code)) {
      $dialog_url = "http://www.facebook.com/dialog/oauth?client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url);

      echo("<script> top.location.href='" . $dialog_url . "'</script>");
    }

    $token_url = "https://graph.facebook.com/oauth/access_token?client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url) . "&client_secret=" . $app_secret . "&code=" . $code;

    $access_token = file_get_contents($token_url);
    $batched_request = '[{"method":"GET","relative_url":"me"},' . '{"method":"GET","relative_url":"me/friends?limit=50"}]';

    $post_url = "https://graph.facebook.com/" . "?batch=" . $batched_request . "&access_token=" . $access_token . "&method=post";
    echo $post_url;

    $post = file_get_contents($post_url);
    echo '<p>Response: <pre>' . $post . '</pre></p>';

You can use CURLOPT_ENCODING per the documentation:

The contents of the "Accept-Encoding: " header. This enables decoding of the response. Supported encodings are "identity", "deflate", and "gzip". If an empty string, "", is set, a header containing all supported encoding types is sent.

This way cURL will be telling Facebook, "hey I understand compressed data, please send me compressed data".

$url2 = 'https://graph.facebook.com/'. $group_id . '/feed' . '?limit=30&access_token=' . $_SESSION['access_token'] ;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url2);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_ENCODING, ''); // enable compression, keep empty to send all supported types
$json = curl_exec($ch);
$data = json_decode($json, TRUE);
