We just migrated a Word Press news portal to SilverStripe. It has around 3-4k posts. Now this become really difficult to manage in admin section. When you login all 4k posts are loaded. Extremely slow

Can somebody suggest how can I load only last few post in admin and mark rest of them as Archive or something?

Here is my code to NewsPost.php

* Defines the Newspost page type

class NewsPost extends BlogEntry {
   static $db = array (
'GalleryImageWidth' => 'Int',
'Featured' => 'Boolean',
'UserPost' => 'Boolean',
   static $default_parent = 'NewsHolder';
   static $can_be_root = false;
   static $has_one = array(
      'Photo' => 'Image'

      //'Gallery' => 'ImageGalleryPage'
      //'GalleryImages' => 'GalleryImage'
   static $has_many = array (
'GalleryImages' => 'GalleryImage'

public function init() {

// Note: you should use SS template require tags inside your templates
// instead of putting Requirements calls here. However these are
// included so that our older themes still work


   function getCMSFields() {
   $fields = parent::getCMSFields();
$fields->addFieldsToTab("Root.Content.Main", new CheckboxField('UserPost', "Post by a Member"));
   $fields->addFieldToTab("Root.Content.Main", new CheckboxField('Featured', "Featured Post"));
   $fields->addFieldToTab("Root.Content.Images", $leadImage= new ImageField('Photo', "Upload your lead image here"));
      $leadImage->setFolderName('Uploads/' .date("Y").'/' .date("m"));
   $fields->addFieldToTab("Root.Content.Configuration", $myField= new NumericField('GalleryImageWidth', 'Image Width'));
      /*$fields-> addFieldToTab ("Root.Content.Gallery", new DropdownField("GalleryID", "Gallery",
         DataObject::get("ImageGalleryPage")->toDropdownMap(), 'Content'));*/
      $manager = new ImageDataObjectManager(
$this, // Controller
'GalleryImages', // Source name
'GalleryImage', // Source class
'MyGalleryImage', // File name on DataObject
'GalleryImageTitle' => 'GalleryImageTitle'
), // Headings
'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
// Filter clause
// Sort clause
// Join clause

$fields->addFieldToTab('Root.Content.GalleryImage', $manager);
return $fields;

// Function for SideBar
function GetSidebarContent($num=3) {

//$randomNumber =
$sidebarContent = DataObject::get_one("SidebarContent");

return false;

$contents = array();

$contents[] = DBField::create('Varchar', $sidebarContent->Content1);
$contents[] = DBField::create('Varchar', $sidebarContent->Content2);
$contents[] = DBField::create('Varchar', $sidebarContent->Content3);
$contents[] = DBField::create('Varchar', $sidebarContent->Content4);
$contents[] = DBField::create('Varchar', $sidebarContent->Content5);


//return new DataObjectSet(array_rand($contents, $num));
return new DataObjectSet(array_slice($contents, 0, $num));
//return new DataObjectSet($contents);


class NewsPost_Controller extends BlogEntry_Controller{
