Product page on Storefront might be loading too slowly because of all the **bulky data** that is has. Only the required information in each particular situation should be loaded.  
Increasing the performance for product with tens (or thousands) of **variations** :

- Don’t load the variations at all. You can control this by [ItemResponseGroup](https://github.com/VirtoCommerce/vc-module-core/blob/dev/VirtoCommerce.Domain/Catalog/Model/ItemResponseGroup.cs).  
Calling the load product API with response group without `Variations` flag:

```auto
IItemService.GetById(id, ItemResponseGroup.Full & ~ItemResponseGroup.Variations)

```

This can be set in theme (Liquid template) as well:

```auto
{% paginate collection.products by 5 params {"ResponseGroup":"Manually set the exact product dependencies to be loaded on this page. E.g., 'ItemInfo'"} %}
   {% for product in collection.products%}
     ....
   {% endfor %}
{% endpaginate %}

```

- Load product variations by a separate query. See this issue for details
