Long server response using wp_oembed_get for custom metas!

Hello!

I use wp_oembed_get function to display video from single URL.

I don’t know what I’m doing wrong, everything seems right.
Here is the code I’m using in content.php:

//video title
<?php echo '<h2>' . get_post_meta($post->ID, 'item_10_title', true) . '</h2>'; ?>

//embeded video

<?php
$videourl = get_post_meta($post->ID, 'item_10_video', true);
$htmlcode = wp_oembed_get($videourl);
echo $htmlcode;
?>

//video description
<?php echo '<p>' . get_post_meta($post->ID, 'item_10_description', true) . '</p>'; ?>

and the same code for next 9 videos…

The thing is, when there’s only one video displayed via custom field, everything is fine, but when I add more videos, page slows down even more.
When there are 10 videos displayed, I have about 3 seconds long server response which is really bad.

When there are no videos added, only video title and description – page loads super fast. I know that the problem is with oEmbed.

Please help. :/
