My order and order details collection query takes too much time suddenly

Question

I am working on order collection query outside magento directory.It is working fine and also providing results. But suddenly fetching records time is more as compare to previous time. Now it takes more time for fetching same record database. Don't know what happens and what to do?

    <?php

$order_collections = Mage::getModel('sales/order')->getCollection()
->addAttributeToSelect('increment_id')
->addAttributeToSelect('entity_id')
->addAttributeToFilter('store_id', array('in' => array('finset' => $storeId)));
$order_collections->setOrder('created_at', 'DESC');

foreach($order_collections as $_order)
{ 

    $incrment_id =  $_order->getIncrementId();//die;
    $ordered_items = Mage::getModel('sales/order')->loadByIncrementId($incrment_id);

    if(count($ordered_items)!=0)
    {
        foreach($ordered_items->getAllVisibleItems() as $item)
        {
            $allproductids[] = $item->getProductId();
        }
    }

    $collection = Mage::getModel('catalog/product')->getCollection()
    ->addAttributeToFilter('entity_id', array('in' => $allproductids));

    $collection->addAttributeToSelect
    (
        array
        (
            'entity_id',
            'name',
            'description',
            'short_description',
            'price',
            'special_price',
            'image_label',
            'small_image_label',
            'thumbnail_label',
            'barcode'
        )
    )->setStoreId($store_id);

    //pr($collection->getData());

load product here and skip other product just load product data

foreach($ordered_items->getAllVisibleItems() as $item)
        {

          $product = Mage::getModel('catalog/product')->load($item->getProductId());

                    $productDetailsImage = $product->load($product_details->getId())->getThumbnail();

                    $x = explode('/',$product_image_url);
                    $loaddata[$product_details->getId()]['image_name'] = end($x);
