We understand how crucial speed is for an online store. This is why we put much effort into making CS-Cart faster with every new version. Backed by advanced web technologies, CS-Cart scores 95 points out of 100 in the Google Page Speed test out of the box. This is the highest score among other top e-commerce platforms.

With CS-Cart, you don’t have to worry that your customers will wait for a page to load. CS-Cart is designed to deliver smooth and seamless shopping to every customer.

Client-Side Optimization

Lazy Image Loading

With lazy image loading the images on your storefront are loaded only when a customer scrolls to them.

Lazy image loading reduces server load and makes a web page load faster.

Deferred Script Loading

Customers cannot see the scripts because the scripts are a part of an HTML page and stand for animations and interactive content. It's important to show what a customer can actually see on the web page first.

Scripts are loaded last and don't block loading of the images and other visual content.

Gzip for HTML, CSS, JS

When a customer opens the webpage, the server starts sending web page files (HTML, CSS, JavaScript) to the customer's browser.

Gzip reduces the size of these files. The smaller the page files, the faster they are delivered to a customer's browser.

CDN Support Out of the Box

CS-Cart ships with the Amazon CloudFront CDN support. All the benefits of a Content-Delivery Network are at your service, in just a few clicks.

CDN is a system of worldwide-distributed servers that store your static data (images, CSS, and JavaScript files). For customers, this means better response time when they access your site, because the content takes a shorter path to their browsers.

Server-Side Optimization

Built-In Cache

The built-in caching engine caches template data and MySQL data into the memory. When CS-Cart needs that data again, the cached template data and MySQL query results are quickly retrieved from the memory.

xCache, Redis, APCu

CS-Cart supports xCache, Redis, and APCu caching technologies.

These accelerators cache CS-Cart data into the memory. Getting the data from the memory is always faster than generating it from scratch.


OpCache accelerates PHP scripts by saving byte codes into the memory. When CS-Cart calls the same PHP script, the pre-cooked byte code is retrieved from the memory.

Retrieving the byte code from the memory is faster than compiling the PHP script again.


HHVM (HipHop Virtual Machine) is a technology developed by Facebook to provide an alternative, faster way to execute PHP scripts.

For now, HHVM is considered the fastest engine for executing PHP scripts. And when PHP is fast, CS-Cart accelerates too.
