Enterprise 1.14.1色板会导致类别页面上的加载时间增加35秒

我们在最新的新站点构建中实现了新的内置色板功能。在类别页面上启用色板时，页面加载时间从2秒变为38 +秒。

我想知道是否还有其他人遇到过这个问题，是否可以给我们指出任何可能的解决方案？

我们已经尝试了EE 1.14.1和CE 1.9.1，并在标准rwd主题上使用了36种可配置产品和色板，并且没有其他模块处于活动状态。

每次用户搜索或过滤类别时，都无法通过缓存来解决此问题，页面再次陷入停顿。

对。我在Mage_ConfigurableSwatches_Helper_Mediafallback :: attachConfigurableProductChildrenAttributeMapping函数上检测到问题。

我对此进行一些更改。这样可以提高性能。

尝试：

1. 复制/app/code/core/Mage/ConfigurableSwatches/Helper/Mediafallback.php到 /app/code/local/Mage/ConfigurableSwatches/Helper/Mediafallback.php。

2. 在/app/code/local/Mage/ConfigurableSwatches/Helper/Mediafallback.php文件移动代码（ll.88-91）

    // normalize to all lower case before we start using them
    $optionLabels = array_map(function ($value) {
     return array_map('Mage_ConfigurableSwatches_Helper_Data::normalizeKey', $value);
    }, $optionLabels);

   直到foreach循环之前。

这是更改的方法：

 /**
 * Set child_attribute_label_mapping on products with attribute label -> product mapping
 * Depends on following product data:
 * - product must have children products attached
 *
 * @param array $parentProducts
 * @param $storeId
 * @return void
 */
public function attachConfigurableProductChildrenAttributeMapping(array $parentProducts, $storeId)
{
    $listSwatchAttr = Mage::helper('configurableswatches/productlist')->getSwatchAttribute();

    $parentProductIds = array();
    /* @var $parentProduct Mage_Catalog_Model_Product */
    foreach ($parentProducts as $parentProduct) {
        $parentProductIds[] = $parentProduct->getId();
    }

    $configAttributes = Mage::getResourceModel('configurableswatches/catalog_product_attribute_super_collection')
        ->addParentProductsFilter($parentProductIds)
        ->attachEavAttributes()
        ->setStoreId($storeId)
    ;

    $optionLabels = array();
    foreach ($configAttributes as $attribute) {
        $optionLabels += $attribute->getOptionLabels();
    }

    // normalize to all lower case before we start using them
    $optionLabels = array_map(function ($value) {
        return array_map('Mage_ConfigurableSwatches_Helper_Data::normalizeKey', $value);
    }, $optionLabels);

    foreach ($parentProducts as $parentProduct) {
        $mapping = array();
        $listSwatchValues = array();

        /* @var $attribute Mage_Catalog_Model_Product_Type_Configurable_Attribute */
        foreach ($configAttributes as $attribute) {
            /* @var $childProduct Mage_Catalog_Model_Product */
            if (!is_array($parentProduct->getChildrenProducts())) {
                continue;
            }

            foreach ($parentProduct->getChildrenProducts() as $childProduct) {

                // product has no value for attribute, we can't process it
                if (!$childProduct->hasData($attribute->getAttributeCode())) {
                    continue;
                }
                $optionId = $childProduct->getData($attribute->getAttributeCode());

                // if we don't have a default label, skip it
                if (!isset($optionLabels[$optionId][0])) {
                    continue;
                }

                // using default value as key unless store-specific label is present
                $optionLabel = $optionLabels[$optionId][0];
                if (isset($optionLabels[$optionId][$storeId])) {
                    $optionLabel = $optionLabels[$optionId][$storeId];
                }

                // initialize arrays if not present
                if (!isset($mapping[$optionLabel])) {
                    $mapping[$optionLabel] = array(
                        'product_ids' => array(),
                    );
                }
                $mapping[$optionLabel]['product_ids'][] = $childProduct->getId();
                $mapping[$optionLabel]['label'] = $optionLabel;
                $mapping[$optionLabel]['default_label'] = $optionLabels[$optionId][0];
                $mapping[$optionLabel]['labels'] = $optionLabels[$optionId];

                if ($attribute->getAttributeId() == $listSwatchAttr->getAttributeId()
                    && !in_array($mapping[$optionLabel]['label'], $listSwatchValues)
                ) {
                    $listSwatchValues[$optionId] = $mapping[$optionLabel]['label'];
                }
            } // end looping child products
        } // end looping attributes


        foreach ($mapping as $key => $value) {
            $mapping[$key]['product_ids'] = array_unique($mapping[$key]['product_ids']);
        }

        $parentProduct->setChildAttributeLabelMapping($mapping)
            ->setListSwatchAttrValues($listSwatchValues);
    } // end looping parent products
}

当您有很多属性选项时，提高性能的可配置色板的其他方法。

例如，如果您有2000个选项并在目录列表中显示36个产品，则在这种情况下，方法Mage_ConfigurableSwatches_Model_Resource_Catalog_Product_Attribute_Super_Collection::_loadOptionLabels()将加入到每个super_attributes选项标签中，并且您将获得2000 * 36 = 72000行。

我重写了此方法，它仅加载2000行而不是72000
