Site Performance: How Wix Improves Your Site's Loading Time
2 min read
Having a fast loading time ensures a smooth and pleasant experience for your site visitors. Wix is always striving to optimize your site's performance and develop new ways to improve loading time.
Automatic Image Optimization
Images can add life and context to your site. Whether you're displaying photography, information, or just adding to your site's feel, it's important that your image quality isn't compromised.
When you upload an image to your site, Wix resizes the image for optimal quality and site loading time. Provided that an image is less than 25mb, there is no need to compress it before uploading, as this is automatically done.
Content Delivery Network (CDN)
To ensure optimal loading speed, Wix uses a system of global cache services and proxy servers, called content delivery network. CDN works by delivering site content to your visitors from the server geographically closest to them.
Content Delivery Network acts as the middleman between Wix servers and your visitors, reducing latency and site loading time.
Defense Against DDOS Attacks
A DDOS attack is a "Distributed Denial-of-Service" attack. These types of attacks overload the servers, and cause them to react slowly or not at all. Wix has a set infastructure that can lessen the results of these attacks, and may prevent your site's loadng time from being severely impacted.
Lazy Loading Images
High resolution images can significantly impact your site's loading time. To ensure a better visitor experience while not compromising your content, Wix uses a technique called Lazy Loading Images.
This technique boosts loading time by replacing high-resolution images with low-resolution versions. The low-resolution placeholders load instantly, even on slow networks, while your high-resolution content loads in the background. Once loaded, the high-resolution images automatically replace the placeholders.
