Webscale VelocityEDGE

Enhance digital experience with improved ecommerce performance

Webscale VelocityEDGE is a revolutionary website performance software custom-built for ecommerce success. Combining intelligent Varnish Caching at the edge with advanced HTML streaming, it transforms the user experience of online commerce storefronts by enabling faster page response, low latency, higher SEO ranking and greater conversions.

Why Ecommerce Needs Intelligent Edge Caching

Nothing else can effectively illustrate the impact of slow page load on an ecommerce business than a quick math:

If 1,000 customers visit your ecommerce website to buy a $100 product, this could illustrate the potential revenue loss due to poor page speed:

  • Potential revenue at 1-second page load time and 3% conversion rate: $3,000
  • Potential revenue at 2-second page load time and 1.50% conversion rate: $1,500
  • Potential revenue at 3-second page load time and 1% conversion rate: $1,000
  • Potential revenue at 4-second page load time and 0.50% conversion rate: $500

In just 4-seconds, potential revenue has dropped by $2,500 due to highly possible lower conversion rate as page load time increases.

Imagine your online store welcomes 10,000 visitors a day! What if your average order value (AOV) is higher than $100? That’s the revenue impact of poor website performance and the reason why ecommerce businesses should invest in an intelligent edge caching solution combined with advanced HTML streaming.

Technical Information

HTML Streaming

HTML streaming, a core feature of VelocityEDGE, is an innovative technique that enhances website performance by delivering web page content in a progressive and optimized manner. Here’s how HTML streaming works:

Progressive Rendering
Instead of waiting for the entire web page to load, VelocityEDGE progressively streams essential HTML content to users as it becomes available. This allows the web page to start rendering almost instantly, providing a faster and more engaging user experience.
Optimized Content Prioritization
VelocityEDGE intelligently prioritizes the delivery of critical HTML elements, such as headers, navigation menus, and calls-to-action. These elements are essential for the initial rendering of the page, ensuring that users can start interacting with the website without delay.
Reduced Time to Interactivity
By prioritizing and delivering crucial HTML content early in the loading process, VelocityEDGE significantly reduces the time it takes for the page to become interactive. Users can interact with buttons, forms, and other elements sooner, leading to a seamless browsing experience.
Seamless User Experience
HTML streaming creates a smooth and uninterrupted user experience, even for content-heavy pages. As users scroll and interact with the website, VelocityEDGE continues to stream additional HTML content, ensuring a continuous and engaging browsing experience.
Bandwidth Optimization
With HTML streaming, VelocityEDGE optimizes bandwidth usage by delivering only the necessary HTML elements in the initial response. This efficient use of bandwidth benefits users, especially those on slower internet connections or mobile devices.
Enhanced Mobile Performance
HTML streaming is particularly beneficial for mobile users, as it minimizes the time it takes to load critical content. With faster load times, mobile visitors enjoy improved page responsiveness and overall satisfaction.
Compatibility with Dynamic Content

HTML streaming seamlessly adapts to websites with dynamic or personalized content. Whether the content changes based on user interactions or real-time data, VelocityEDGE ensures that relevant and up-to-date HTML elements are prioritized and delivered promptly.

Varnish Cache

Varnish Cache, a fundamental component of VelocityEDGE, is an open-source HTTP accelerator that sits between the web server and the client, acting as a reverse proxy. Here’s how Varnish Cache works:

Caching Mechanism
Varnish Cache stores copies of web pages, images, CSS, and other static assets in its high-speed memory, known as the cache. When a user requests content from a website, Varnish Cache first checks if the requested content is already stored in its cache.
Fast Content Delivery
If the requested content is available in the cache, Varnish Cache delivers it directly to the user without having to query the origin web server. This significantly reduces the time it takes to retrieve and serve the content, resulting in faster page load times and improved user experiences.
Cache Invalidation
To ensure users receive the most up-to-date content, Varnish Cache employs cache invalidation mechanisms. When content on the origin server is updated or changes, Varnish Cache automatically refreshes the cache for that specific content, ensuring users always access the latest version.
Strategic Caching
Varnish Cache can be configured to cache specific content strategically. It allows website administrators to set cache rules based on URLs, HTTP headers, or cookies. This intelligent caching approach ensures that critical content is cached, while dynamic or personalized content is fetched directly from the origin server.
Load Balancing
Varnish Cache can also perform load balancing across multiple backend servers, distributing user requests to optimize server resource usage and ensure efficient content delivery.
Grace Mode
In the event of backend server failures or temporary unavailability, Varnish Cache can operate in Grace Mode. It serves cached content for a short period, ensuring continued access to critical resources while the origin server is restored.
HTTP Purging
Varnish Cache supports HTTP purging, allowing website administrators to invalidate specific cache entries manually. This enables rapid cache invalidation in response to content updates or changes.
Customization and Configuration

Varnish Cache is highly customizable and can be configured to suit specific website requirements. Website owners can tailor caching policies, rules, and behaviors to optimize cache efficiency and performance.
