Migrating image galleries from other site to wordpress

Hello everybody. I’m trying to upload/import old site galleries to WordPress with script as custom_field but after 5-6 galleries it gives 503 error. Maybe anybody knows how to optimize the code to do all galleries.
My server settings: max_execution_time:1200, memory_limit: 512M, post_max_size: 128M

		$info =  file_get_contents('data.php');;
		$data = json_decode("$info",true);

    
function Generate_Featured_Image( $image_url_arr, $post_id1, $image_date  ){
        ob_start();
        foreach ($image_url_arr as $image_url){
            
        $post_id = false; 
   require_once(ABSPATH . 'wp-admin/includes/file.php');
   $tmp = download_url( $image_url );
   // Set variables for storage
   // fix file filename for query strings
   preg_match( '/[^\?]+\.(jpe?g|jpe|gif|png)\b/i', $image_url, $matches );
   $file_array['name'] = basename($matches[0]);
   $file_array['tmp_name'] = $tmp;
   // If error storing temporarily, unlink
   if ( is_wp_error( $tmp ) ) {
    @unlink($file_array['tmp_name']);
    $file_array['tmp_name'] = '';
   }
   $time = $image_date ;
   $file = wp_handle_sideload( $file_array, array('test_form'=>false), $time );
   if ( isset($file['error']) ) {
    return new WP_Error( 'upload_error', $file['error'] );
   }
   $url = $file['url'];
   $type = $file['type'];
   $file = $file['file'];
   $title = preg_replace('/\.[^.]+$/', '', basename($file) );
   $parent = (int) absint( $post_id ) > 0 ? absint($post_id) : 0;
   $attachment = array(
     'post_mime_type' => $type,
     'guid' => $url,
     'post_parent' => $parent,
     'post_title' => $title,
     'post_content' => '',
   );
   $id = wp_insert_attachment($attachment, $file, $parent);
   if ( !is_wp_error($id) ) {
    require_once ABSPATH . 'wp-admin/includes/image.php'; 
    $data = wp_generate_attachment_metadata( $id, $file );
    wp_update_attachment_metadata( $id, $data );
  }  
  $res2[] = $id;

}
set_post_thumbnail( $post_id1, $res2[0] );
update_field('galerijos_nuotraukos', $res2, $post_id1 );
echo ob_get_contents();
ob_end_flush(); 
}       

        

        $i=0;
        $my_post = array();
        foreach ($data['title']  as $post1){
            if (empty($make_data[$i])) {
                $make_data[$i] = "2016-05-01";
            }
            $my_post = array(
             'post_title' => $post1,
             'post_content' =>'',
             'post_status' => 'publish',
             'post_type' => 'galerijos',
             'post_date' => $make_data[$i],
          );
            $image_date = str_replace("-","/",$data['data'][$i]);
            
            $post_id = wp_insert_post($my_post);

                Generate_Featured_Image( $data['img'][$i], $post_id, $image_date );

            
             $i++;
        }
