REPORT: State of the Union for Ecommerce Page Speed & Web Performance [Spring 2013]

27 March 2013

It is a widely held belief that leading ecommerce sites must be getting faster, rather than slower, thanks to our increasingly souped-up browsers, devices, and networks. But is this actually the case? Our latest retail web performance survey indicates otherwise.

Since 2010, we've been measuring the performance of the top 2,000 retail websites (as ranked by The purpose of this research has been to gain ongoing visibility into the real-world performance of leading ecommerce sites – to learn how these sites perform for visitors sitting at home using the internet under normal browsing conditions.

In December 2012, working with our soon-to-be parent company Radware, we tested the load times (in Internet Explorer 9, Firefox 17, and Chrome 23) and page composition of the Alexa Retail 2000, and then analyzed this data alongside our benchmark data.

The goal was to identify trends and find answers to questions such as:

  • Assuming that page speed is an increasingly urgent issue for online retailers, has this urgency translated into faster pages over time?
  • How quickly have retailers moved to adopt core performance best practices, such as using a content delivery network (CDN)?
  • How do the top 100 retail sites compare to the top 2,000?
  • How do different browsers compare in terms of page rendering speed, and what does this comparison mean?

The answers -- some of which may surprise you -- are in the report State of the Union for Ecommerce Page Speed & Web Performance [Spring 2013], which is now available for free download.

REPORT: State of the Union: European Page Speed and Web Performance

20 March 2013

One-third of Europe's top retail websites aren't meeting the performance demands of online shoppers. This was the key finding of a new report released by our parent company, Radware, in conjunction with Level 3 Communications.

A survey of the top 400 ecommerce sites in Europe found that:

  • The median load time for first-time visitors was 7.04 seconds.
  • 1 out of 4 sites took more than 10 seconds to load. 
  • 1 out of 3 pages contained 100+ resource requests. Page resources -- including CSS, JavaScript, and image files -- are the content objects in every web page. Each of these resources represents one server round trip that is needed to pull all the page’s resources to the user’s browser. More server round trips typically equal longer page render times.
  • 79% of sites did not use a content delivery network (CDN). CDNs cache page resources closer to the relevant end users, allowing resources to make shorter round trips and speed up rendering. Yet only 1 out of 5 of the leading online retailers currently uses a CDN.

Radware VP application acceleration Joshua Bixby had this to say about this report:

"These findings are a wake-up call for online retailers in Europe. In today's hyper-competitive retail climate, site owners need to know that 7-second load times are simply much too slow, and they need to realize that shoppers are not oblivious to the issue of page speed. When fully three-quarters of sites are disappointing end users, that number can’t be ignored."

New Web Performance Today podcast: Mike Belshe (Twist)

14 March 2013

Former Googler Mike Belshe is the inventor of one of the most important protocol changes to improve the performance of the web over last ten years -- Google's SPDY protocol -- and it was an honour to welcome him to our virtual studio.

Among other things, SPDY makes pages faster by compressing some page resources, preloading select resources into the user's browser, and extending what the browser can do allowing multiple concurrent streams over a single connection (thereby reducing the number of server round trips).   

Mike talked with podcast host Joshua Bixby about the fact that, even at Google, proposing a paradigm-shifting initiative like SPDY can meet with raised eyebrows:

I think the place that I really added value was in the start-up of nature of [SPDY]. Even though I was at Google when we started this project, and everybody wanted the web to go faster inside of Google, we kind of worked around it and said "Hey! We can do this with a better protocol." And people were, like, "A better protocol? You're never going to get that to work. Even if you got Google to do it, who else would do it? Nobody else would support it. It will fail for sure."

Mike and Joshua also talked about Twist, Mike's latest experiment that could change how we think about time, as well as the inner workings of the IETF.


New Web Performance Today podcast: Tim Morrow (Betfair)

7 March 2013

Continuing the chain of performance industry pioneers that have visited the podcast so far, this week Joshua Bixby interviews another pioneer: Tim Morrow. Tim was an early evangelizer of the business value of performance and, more recently, he's a strong advocate for creating customer-facing performance promises.

Tim and Joshua sat down and talked about a wide range of topics, including how to take real-time action on customer measurement and why thinking about third-party content keeps Tim up at night.


New Web Performance Today podcast: Joshua Marantz (Google)

28 February 2013

Tools like Google's PageSpeed and mod_pagespeed are an integral part of most developers' web performance toolkit. This is why it was such an honour to get Joshua Marantz, one of the key movers and shakers behind these projects, inside our virtual studio.

In this week's podcast, he and host Joshua Bixby crack the hood and talk a bit about the inner workings of PageSpeed and mod_pagespeed -- their similarities and their differences.

They also discussed a number of other burning questions, such as how to handle concerns about front-end optimization (FEO) and site breakage, whether or not browsers and servers will ever take on FEO as an automatic function, and why the performance industry is inundated with people named Joshua.


New Web Performance Today podcast: Aaron Peters (Turbobytes)

21 February 2013

The content delivery marketplace is a changing as quickly as it's growing, and in this week's podcast, Joshua was lucky to talk with one of the movers behind this change.

His company closely monitors the real-world performance of six global CDNs, and then ensures that site owners' content is always delivered by the fastest one. 

In this week's podcast, Aaron talks with Joshua about why all CDNs aren't equal all the time, why the upcoming new resource timings API is going to be awesome, and why so many web shops still need to get their performance basics right.


New Web Performance Today podcast: Josh Fraser (Torbit)

14 February 2013

In this week's podcast, Joshua talks with Josh Fraser, CEO of Torbit, a provider of real user measurement (RUM) and dynamic content optimization (DCO) solutions. They talk about discovering the web performance path, how performance has changed from a technical metric to a business metric, advice for young entrepreneurs, and tech predictions for 2013.
