Ready for FIFA-world-cup-2018? What the performance graphs mean.

Prepare for your upcoming traffic peaks - like FIFA World Cup 2018

Is your site ready for peak traffic? How can you prepare for your upcoming traffic peaks? It’s more than just Black Friday and Cyber Monday for many businesses. In fact, one of the busiest traffic periods is coming up: FIFA World Cup 2018. (More about it later.)

No matter what’s coming your way, we want you to be planning for your peak traffic times. And we also recommend load testing.

If you’re not doing it already, load test now before these traffic peaks hit.

Run load tests, ratcheting up the test size until your site’s performance degrades, adjust, and repeat. Keep trying to overwhelm your site with traffic  and simulated, virtual users (VUs). Those peak tests help you with momentary, brief traffic peaks, like on Black Friday or Cyber Monday.

But what happens when traffic goes up and stays up - for a month of the FIFA World Cup - or as a matter of course? Those tests might not help you plan for  a sustained load that lasts much longer.

To better test that, you need to not just be consistent, but to be continuously testing. Use LoadImpact to create a testing script and run it frequently, even daily. This helps you better gauge how your site performs over time.

The best approach: integrate load testing into your continuous delivery and continuous integration (CD / CI) processes so you’re continually ensuring maximum performance from your site.

But what exactly do the performance graphs from your consistent, continuous, repeated tests tell you? Should the line be going up? Down? Staying flat?

Take a look at this example:

Here’s the same test, run over time. This performance trend is exactly what you *don’t* want to see. With the same load, the app is performing worse: the response time, shown in milliseconds (ms), is getting bigger. Ideally, the response time - the trend line - should be drifting downwards, or, at worst, staying flat.

That’s why a consistently applied load test can illuminate issues before they become a big deal with a peak traffic period like the FIFA World Cup. As promised, here’s some more about it. If you’re not a football (soccer) fan, here’s a quick primer: unlike other sports, the world championships happen every four years, not every year. And it’s a real world championship, bringing together 32 teams from countries around the world. Also unlike some other sports, the FIFA World Cup takes place over about a month (14 June to 15 July 2018) at various locations in Eastern Russia, with the final match in Moscow.


We’re choosing the FIFA World Cup as an example: even what seems like an unrelated event might affect your business and the traffic you need to anticipate. With the World Cup, you would, of course, expect peak traffic leading up to the events, through the events, and for at least a little time afterwards. Events like the World Cup show a sustained peak, and in this case, over the course of a month.

Such an event affects more than, say, companies who sell team gear, football (soccer) equipment, and the hosting venues. Those in the travel industry, as well, should anticipate demand in months leading up to the events. Fans from around the world will be traveling to cheer on their favorite clubs. Even media sites can expect increased traffic, and not just in European time zones, as fans track scores.


Consider how the FIFA World Cup 2018 might affect your summer traffic - and what other events you should watch out for. Are there industry trade shows, regular news events or holidays? Set your calendar and get testing.

Happy testing!
