One of the most provocative findings in our latest State of the Union for Ecommerce Web Performance was the fact that using a content delivery network correlated to slower performance for retail sites. In today's post, we'll explore what this finding means (hint: correlation doesn't mean causation) and why you still need a CDN in your performance toolkit.
A typical leading ecommerce website takes longer to render than it did just three months ago, top sites are slower than the rest of the pack, and sites that use a content delivery network (CDN) are slower than sites that do not. These are just a few of the findings detailed in our latest research into the performance of the top 500 retail sites.
If you go looking for case studies that prove the business value of improving website performance, chances are you’ll encounter a number of studies that focus on obvious ecommerce metrics like cart size and sales. But there are a number of other ways that improving performance can move other business metrics. Today, I want to highlight a few of these metrics using some customer case studies.
Since we began tracking the performance of the top 500 retail websites back in 2010, web page speed has migrated from the technology fringe to center stage, due in part to the numerous case studies from large and small companies demonstrating the relationship between site speed and business KPIs like revenue and conversion rate.
Yet despite all this attention, the question remains: has there been a positive impact on the websites we use every day? Our latest ecommerce performance study suggests not.
A couple of weeks ago, I used this space to answer the question of how front-end web performance optimization (WPO) solutions complement CDNs. Today, I’m going to talk about ADCs and WPO as complementary solutions, by explaining how WPO picks up where your ADC leaves off.
The performance poverty line is the plateau at which your website’s load time ceases to matter because you’ve hit close to rock bottom in terms of business metrics. If your pages are well below the performance poverty line, making them a couple of seconds faster doesn’t help your business. Here’s how to find the poverty line for your site.
If you’ve ever been handed a pile of performance data and been stymied by the various measurement terms you encounter, you’re not alone. Even within our industry, standardizing our language is an ongoing challenge. In this post, we’ll walk through five of the most commonly used measurement terms, define them using language a normal person can understand, and talk about when you should care about each.
Most people have a rough idea that latency has something to do with the delay in moving content from the host server to the user, but when pressed, they struggle with explaining the real-world implications of latency on application performance. In this post, I'm going to explain what latency is, its impact on page load, and how we can fight back.
