site speed

Web performance just became seriously mainstream

We’ve been saying for months that this year is going to mark a new highwater point for site speed. I think it’s safe to say that it doesn’t get much more mainstream than a two-minute segment on CNBC’s Power Lunch.

CNBC: Retailers need for speed videoThis segment hits all the key points: the fact that users demand fast websites, the relationship between site speed and revenue, and the need to deliver fast sites to mobile users. I don’t know about you, but to me, this is one of the most exciting pieces of performance-related content I’ve seen in a long time.

Since this video focuses on Black Friday and Cyber Monday (and the newly dubbed Cyber Sunday), I should mention that over on the Strangeloop blog, we’ve rounded up a set of relatively simple (and free) fixes you can make to your site to give it a performance boost before the weekend.

The relationship between faster mobile sites and business KPIs: Case studies from the mobile frontier [Velocity EU]

As promised, here’s the slide deck from my Velocity keynote. A little back story for those who didn’t attend: this data was gathered over many months of the beta of Strangeloop’s Mobile Site Optimizer. It wouldn’t have been possible without the generous participation of two of our customers. They would prefer not to be named, but I’d still like to thank them here.

If you have any questions, please let me know in the comments or ping me on Twitter.

Preview of my mobile keynote slides for Velocity Europe

Tomorrow (Tuesday) morning at 10:35, I’ll be sharing some never-before-released case study data about mobile performance to the Velocity Europe crowd. To give a taste of what I’ll be talking about, here’s a sneak peek at a few of my slides:

Velocity Europe: Mobile Case Studies: M.site traffic & final sales

Velocity Europe: Mobile Case Studies: Impact of site delays on returning visitors

Velocity Europe: Mobile Case Studies: Impact of network quality and performance on bounce rate

I hope to see you there. I’ll be sharing the full slide deck shortly after my session.

There’s a great speaker lineup at this inaugural event. My schedule is filling up fast, but here are some of the sessions I’m hoping to attend:

If you’re at Velocity, too, I’d love to chat. Send me a note or ping me on Twitter.

Speed tests: How fast are China’s top websites?

A couple of months back, Strangeloop released a report about the load times of North American and European sites in China — arguably the fastest growing e-commerce sector in the world. We found that the average load time for these sites was just over 16 seconds.

In my post about the report, Steve Souders asked a great question: To make the case that luxury sites need to be faster, it would be great if you could compare their load time (16.2 seconds) with the load time of popular Chinese sites.

Steve’s question has been percolating on a back burner (I have a lot of back burners), and I was reminded of it when looking at Mary Meeker’s slides from her presentation on internet trends at the recent Web 2.0 Summit.

This slide in particular jumped out:

Of the top 25 websites, six are based in China. While none of these sites come even close to the top four U.S. sites in terms of profitability and valuation, it’s important to remember that this is an online marketplace that is still in its babyhood. By 2015, China’s e-commerce base is expected to increase by almost 400%. It’ll be interesting to see what this table looks like then.

But getting back to Steve’s question, I thought this would be a good time to run some tests and see how China’s top sites compare to the sites we tested in our study. (I used the same parameters: Testing via WebPagetest‘s location in Jiangsu, China, using Internet Explorer 7.)

Page load times of leading Chinese websites

Website Load time (seconds)
CDN detected?
Sina.com 20.818 No
Ctrip.com 2.554 Yes
Alibaba.com 4.877 No
163.com 21.139 No
Tencent.com 27.468 No
Baidu.com 1.706 No
Average Chinese site
13.102 17%
Average NA/EU site
16.2
29%

A few thoughts

  • This is a tiny sample size, of course, but it’s still an interesting snapshot of how China’s top websites fare when it comes to performance.
  • There’s a clear performance divide between verticals, and these correlate closely to the same performance divide I’ve observed in western-based sites. The news sites — Sina and 163.com — experienced 20+ second load times. The e-commerce sites — Ctrip (travel) and Alibaba (retail) — were much faster, with sub-5-second load times. The search site Baidu was the fastest of the bunch, while, ironically, the internet service provider Tencent was the worst. (I suspect that competition isn’t a concern for them.)
  • Only one site, Ctrip, uses a content delivery network.
  • And returning again to Steve’s question, while the overall average load time of just over 13 seconds wasn’t much lower than the 16 seconds we recorded for western sites, it should be noted again that the top e-commerce sites did load in under 5 seconds. From this, we can deduce that leading e-tailers in China are taking performance seriously — which means that western e-tailers need to do the same in order not to get left behind in the global marketplace.

“Phone rage”: How people react to slow mobile sites

This proves that, if you have a question, there’s probably been a study to answer it. When we were preparing to launch our Mobile Site Optimizer, I found myself wondering if there are any numbers on “phone rage” (my term).* It took about 30 seconds to track down this poll, conducted for Tealeaf by Harris Interactive, which finds that when mobile sites and devices perform badly, their owners don’t always handle it well.

Graph: Mobile rage: How people react to slow websites

Among those who have experienced problems conducting mobile transactions, 23% have cursed at their phones; 11% have screamed at them; and 4% have thrown them.

*You know, like road rage, but directed toward your poorly performing phone rather than the guy who just cut you off in traffic. Come to think of it, road rage and mobile rage probably intersect in the real world, but it scares me to think about this for too long.
