I recently read an article in ComputerWeekly describing how TFL had redesigned their website using HTML5 to optimise performance across multiple device types. I was interested to see how the new site was handling the likely increase in traffic due to the tube strike.
Prior to the HTML5 re-write the last major redevelopment of this site had been in 2007, well before the proliferation of mobile devices, now used daily to check for travel updates or plan journeys. 75% of Londoners visit the TFL website regularly and there are 8 million unique visitors per month.
I was in London earlier this week so I, along with millions of other commuters, wanted to keep up to date with the news of the tube strike. I, like many others, turned to my smartphone for answers. The site performed well on my Android phone, so I wondered whether the increase in traffic had caused any performance degradation.
At Trust IV we have developed an in-house application to test the performance of websites, we monitor performance for several hundred sites, each of which is categorised into a relevant business sector. TFL was already being monitored in our “travel” category. I was impressed to see that the website was the 3rd fastest travel site monitored today with a page response time of <1.2 seconds. The site developers should be pleased with themselves.
Although occasional spikes in response times were observed (which is common when monitoring in this way); on the whole the site remained responsive throughout the day. Average response times appear no slower today than they were last week (the chart below shows response times in milliseconds).
If only more of the sites that I visit regularly performed as well as this.
Get in touch for more information about our “Test The Market” monitoring application and how it can give you insights into your own website performance and see how your performance compares with your competitors.

According to the Danone website, “Baby & Me, created by BETC, shows a street full of people rediscovering their inner youth – and dance moves – as their reflections reveal the baby versions of their adult selves.” If you haven’t seen the advert, you should watch “Baby & Me” on YouTube, it’s fantastic; a perfect example of a viral marketing campaign with over 59 million YouTube views. This advert builds on the success of their “Roller Babies” campaign from a few years ago (69 million views). I’ve shown it to my children and my wife and everybody I’ve mentioned it to seems to have seen it. Evian is reaching a mass market with relatively little TV advertising spend.
To capitalise on the success of the advert, Evian has commissioned the production of a “Baby and Me” app for iOS and Android. On the face of it, this looks like a great idea. The application takes a picture of you as an adult and then uses pattern matching to identify over 70 facial features in a database of baby pictures. The application then creates a composite image of you as a baby. This has great potential for social sharing of images and it isn’t hard to see how this could help to ensure that even more people get the “Release the inner you” message from Evian.
There is no doubt that viral media is a great marketing tool and mobile apps are a great way to use peer interaction and socialisation to spread a message quickly. All good news so far from a marketing / PR perspective, but…….
…….There’s always a “BUT” isn’t there?

The Evian app is sadly disappointing. Anybody who downloads an app that doesn’t work first time is highly likely to delete it and never use it again. Negative publicity from colleagues and friends who can’t use the app will do a great deal to damage any positive marketing messages that the app was intended to create
It is highly likely that the application designers and developers have been forced to work to a difficult schedule to get this application to market. Whilst individual teams may have all tested their application components; it is highly likely that proper end-to-end testing, including testing over relatively slow 3G and Wifi networks has not been done. Performance testing is crucial for applications like this, a poor user experience will result in users abandoning the application and never downloading it again.
So what went wrong?
Whilst performance testing is a well-established profession……
…testers need to evolve.
15 years ago testers needed to understand thick clients and complex client-server apps.
10 years ago, web applications dominated the market and testers skills (and pay rates) started to fall.
5 years ago, Web 2.0 and mobile technologies started to develop and many testers failed to understand the complexity of more complex multi-tier web applications.
Now testers need the ability, skills and tools to test across multiple devices and multiple networks and need a deep understanding of application architecture to ensure application stability, scalability and performance under load.
Many testers don’t have the required skills or testing tools to test complex multi-tier applications across different devices and network topologies. Evian have used big-hitting media companies, BETC Digital and B-Reel, to develop their application…. I bet they’re wishing that they had the application tested properly by an independent testing specialist before this week!
My electricity supplier in the UK recently sent me a electricity consumption meter which tracks energy use in real time and displays in on a small LCD panel. This has proved to be a real eye opener for me and has helped me to see how much power is used by a variety of devices in the house. I’ve found myself checking the meter at regular intervals and I’m getting good at working out which things are powered on just by checking the meter!

I’m one of those geeky types that likes to leave my home PC on all the time. This means that when I’m away from home, I can connect to the PC remotely and pick up files or refer to old email archives that I don’t keep on my laptop. I haven’t given this much thought until now but I checked the power consumption of my PC and saw that it draws 250W – 300W whenever it’s powered on. I did some rough calculations to see what this was costing me and I was surprised.
Daily power use for my PC = 0.275 KW x 24 = 6.6 KWh
Annual power use for my PC = 6.6 KWh x 365 = 2409 KWh
Average cost in the UK for 1 KWh = £0.14
Annual cost for running my PC all the time = £0.14 x 2409 KWh = £337.26
This made me think about turning my PC off more (as my wife has been suggesting for years) 😉 But I don’t want to lose the ability to turn it on remotely and get access to files….. hence my use of WOL (Wake on Lan).
I recently bought a Raspberry Pi and I’ve been tinkering with it for a while, I’ve used it for time lapse photography and general experimentation. I’ve also put one in the Trust IV office in Manchester which operates a webcam. I thought that I could use the low-powered Raspberry Pi to wake up my high-powered PC when I need it and I’d enable power management on the PC to put the PC to sleep when it isn’t in use.
Installed “wakeonlan” on the Pi, using the command [sudoapt-getinstall wakeonlan]
Installed Apache on the Pi, using the command [sudo apt-get install apache2]
Installed PHP5 on the Pi using the command [sudoapt-getinstallphp5]
Wrote a small PHP script that sends the wakeonlan command to my PC.
Changed the default port for the webserver
Enabled port forwarding on my router to forward HTTP requests from outside to the Pi.

The PHP script (above) is pretty straightforward and uses the “exec” command to simply execute the wakeonlan command. I may improve this to give myself some visual feedback to show that the magic packet has been sent to the PC. For now I’m just happy that I can reduce my energy consumption and still access my PC remotely whenever I want to.
Assuming that this gives me a 50% energy saving, this should reduce the electricity bill by more than £150 per annum.
