The contest is launched at, starting from today and ends on Nov 30th, 2010. The contest is open for participation. To participate, anyone can simply register at as a contestant, download the real world webpage example selected by the organizers, optimize the site, upload the optimized site to at any time, and will be able to see the optimization result immediately online. Winners will be decided using open web performance measurement tools, as well as manual checks by a selected group of judges.

“The growing importance of web performance is well documented, from the fact that Google now incorporates page load time into search engine rankings, to Mozilla’s ability to increase Firefox downloads by 15 percent, simply by decreasing load time by 2 seconds. Smart companies such as Google have been using web performance as a competitive differentiator for many years”, said Vincent Voyer, Zeroload's founder. “However, many other businesses have not fully realized how performance can be the secrete sauce. We are organizing this first international web performance contest to help more people take advantage of the opportunities enabled by faster web sites”.

Contest Awards will be given on the following categories: Best Yottaa Score, Best onload & start render, and smallest number of requests & total size. Prizes are provided by contest sponsors, including iPad, iPod, and technical books. The judges of the contest include web performance experts such as Éric Daspet, Stoyan Stefanov, Jean-Pierre Vincent, and Vincent Voyer. Other contest sponsors include AlwaysData (a web hosting company providing both dedicated server and shared hosting services) and Catchpoint Systems (a web performance monitoring software company).

 “Site performance has become an increasingly important factor to boost conversion rates, influence search engine rankings and increase overall user engagement”, said Robert Buffone, Yottaa’s co-founder and CTO. “Speed is the differentiator. Performance is an opportunity. Better web performance can result in better business performance. At Yottaa, we are very glad to be able to contribute to the contest. Performance matters.

Webperf contest rules


Optimize a real world web page et try to perform in the three categories :

  • Best YOTTAA score computed from
  • Best onload & start render times computed from
  • Smallest number of requests & total size computed from

All measurements on will have these settings : Paris, IE7, DSL.
Your optimized version of the webpage package have to be sent on our server.

Webpage used for the contest

One of the french biggest ecommerce websites : was kind enough to lend us one of their webpage.

The original webpage url is :

On the register page you'll find the packaged version of this webpage. This package is the webpage you'll have to optimize and send back to us

Features to keep

There's a certain number of features to keep from the original webpage, i.e. you can't break features for performance optimizations :

  • Search and autocomplete
  • Smooth toggle when clicking on the arrow next to "mon panier" label
  • Central slider with automatic and manual switch
  • Top menu and hovering submenus
  • Ajax calls for "x produits trouvés"
  • Tracking system must be the same (s_code)
  • Any other features you would notice

Sending your optimizations

After your registration is ok, you'll receive your ftp credentials within 24 hours

Each participant will have access to his FTP directory on 4 different domains :


This will allow you to use domain sharding for example.

All measurements will be done on your "index.html" file on the domain. That means you can't change the name of the index file.


  • No cheating ! Displaying a big JPG for the complete website is cheating (even if you strip exif data, yes!)
  • No server side code (it is disabled)
  • User experience should not be degraded (but you are welcome to improve it), which is to say, for example:
    • Once page is loaded, all original features must still work
    • Accessibility must be preserved (although you can improve it)
    • SEO must be preserved (although you can improve it)
  • Use our servers, you can't host files on other domains than *
  • Use htaccess file to tweak your directory configuration if it does not fit your needs
  • CSS1-2-3, canvas, svg, JavaScript (inline, external, minified, ...), dataURIS, MHTML, defer, async, *insert crazy technique* ALLOWED
  • We'll be using IE7 for WPT but that do not means you can't use new techniques
  • You may deliver a page wich is not an exact pixel per pixel copy and do some arrangements, provided you respect the "user experience" rule

The main rule is : Do it as it was your own website, your customers & your design. Do not ruin everything for performance.

If a typical product owner would refuse your change, you may be outside the rules. Askif you're really unsure, we'll also contact you if there's a problem.

The judges will have the final word on what they think is acceptable or not, especially when two participants have very similar timings and scores.
