# Does Regios Discounts Affect Site Speed?

We sometimes get asked if our app slows down storefronts. Here’s what you need to know:

## Cart & Checkout Discounts

These use Shopify’s **Discount Functions API** and **run entirely on Shopify’s servers**.

✅ **No impact** on your store’s page load speed
✅ Shopify enforces strict performance limits and timeouts

## Product Page Discounts & Auto Add to Cart

These features **do use JavaScript** to update the storefront experience.

* JS is **loaded asynchronously** and **does not block rendering**
* There’s **no effect on initial page load**
* Features won’t work until the JS finishes loading

👀 Why not use Liquid instead? [Read this article](https://regiostech.crisp.help/en/article/why-do-you-use-javascript-instead-of-a-liquid-snippet-1ckcasu/)

## Current and Planned Optimizations

* We’ve already **reduced JS bundle size** substantially
* We're planning to consolidate code further to reduce the size of individual extensions.
