Black Friday 2011

Black Friday 2010 is upon us.

Now, what are you doing to get your Web site ready for Black Friday 2011?

While this may be a shocking slap in the face, it is a very realistic one. If you take what happened today, and what you think may happen over the next 4 weeks, what will your organization really need to be ready for next year – same time, same place?

You were thinking about that as you got ready for this year, right?

Well, it’s never too early to start planning. Here are some items you should be putting on your January 1 2011 wish-list.

  • Better Web monitoring. What did you get caught without any insight into this year? Where do you need to get more information? Inside or outside the firewall? Third-party components? What surprised you this year?
  • Earlier load testing. Is it less stressful to test your capacity and focus your optimization efforts in Q1 2011 or in October 2011? The advanced customers we work with start running their load tests in April, not September. How much change can you make to your systems by the time you discover a problem in September?
  • Real-world inputs and projected growth. When you take your analytics data and project your growth for next year, are you factoring in macro-economic inputs? No, I’m not an economist, but if the economy isn’t projected to grow as fast, aim your projected growth for the middle of the range for testing, not for the top-end.
  • Test capacity to the maximum. No, this is not mutually exclusive of the previous item. When you test your capacity, you want to make sure that you know exactly how much growth it can take. Even if growth is not projected to break it this year (and you can prove this with load testing), how about in 2012?
  • Mobile Commerce Readiness. Mobile is the latest buzzword. But do you have a real plan to handle a rush of people checking your prices from other stores on Black Friday? And if they want to buy it right there, can they? Mobile is not a separate silo; All sales channels make you money, so stop treating them differently. If you are going mobile, do it with a plan that scales with sales.

Whatever you do, don’t rest on your laurels (or bed of broken glass, depending on how your day went). Have a plan. Write it down. Set some deadlines.

Give yourself a head start.

Black Friday 2011 is only 364 days away.

Black Friday 2008: The pain, the horror, the suffering

The GrabPERF Black Friday Dashboard is done for another year and there were two performance victims that suffered the most at the hands of the onslaught of bargain-hunters in the area of Web performance.

Some caveats that I need to mention about the GrabPERF measurement methodology.

  1. Only the base HTML file of each site is measured.
  2. Only the base HTML of the homepage is measured. This means that any issues that arose in the shopping process were not captured.

All of the sites in the GrabPERF Holiday Retail Measurement Index can be continually monitored on the GrabPERF Black Friday Dashboard. This page will be available until January 1 2009.

That said, the two primary performance victims this year are HP Shopping and Sears. We focus here on those that did not do that well because sites who have met the Web performance challenge and survived to fight another year are not as interesting from a learning perspective.

HP Shopping

HP Suffered the greatest response time problems, by effectively becoming unresponsive as of 09:00 EST. The greatest affect on overall response time came as a result of the First Byte time metric which is a solid proxy for measuring the server or application load, as it is the time between the initial client HTTP request and the server’s HTTP response.

Factored into the poor performance analysis is the fact that GrabPERF only captures data for the base HTML object. If the performance seen here is carried over to the download of all of the graphical content on the page, I would be surprised if anyone was able to make any kind of purchases on the HP web site on Black Friday.

Today, performance has returned to substantially lower levels, indicating that this application was simply not ready for the amount of traffic it received, or ran into a completely unexpected issue when the load increased.

Recommendation for 2009: Load Test the application using this year’s traffic metrics as a baseline for validating the scalability of the application.

Sears

Sears is a returning visitor from last year’s Black Friday measurements. Unfortunately, they return for exactly the same reason that they were on last year – scaling/capacity issues that appear as errors.

And these are the worst kind of errors. As can be seen in the graphic below, the Sears Web site announced to the whole world that they had over-reached and that they could not handle the incoming volume of traffic.

What is interesting is that Sears owns properties that survived the day very well, namely Lands End. The question that must be posed is why does the parent site fail so badly when the child sites handle the traffic without difficulty?

Recommendation for 2009: Load testing for capacity, and meeting with the Lands End team to understand what they are doing to handle the load.
