Suggest it for better performance

I have also experienced this performance issue.

The issue here is that the code will load every richsnippet every time getSnippetByProductIdAndStoreId() is called, because it uses getItemByColumnId(). This is critically bad for performance.

My suggestion is to change

$snippet = $col->getItemByColumnValue('product_id', $product_id);

to something like

$col->addFieldToFilter('product_id', $product_id);
$snippet = $col->getFirstItem();
