MTGx is the digital accelerator of Modern Times Group, and is focused on leveraging MTG’s digital assets and industry leading content portfolio, to create and deliver world class entertainment experiences.
In the fall of 2013, they acquired the rights to broadcast the 2014 winter Olympics throughout Sweden.
With Sweden being quite competitive in winter sports, MTGx expected there to be a significant amount of traffic accessing their various sites as well as the live streaming offered on os.viaplay.se.
The Project Scope
Load Impact was commissioned to help excite a series of performance tests aimed at
stressing several worst case scenarios. The worst case scenarios were:
Simulate the average user load on the tv3.sehomepage and then execute a sudden usage
spike before users click the link to the olympic website - os.viaplay.se. Expected 30,000
concurrent users at peak usage.
Spike test in excess of 1 million users who will hit thetv3.sehomepage, which should be fully cached in varnish.
Test to see where the bottlenecks are, fix and then retest to confirm the improvements.
The test covered:
Results: os.viasat.se and SotchiJunior.se
both. Goal was stability at 50 000 concurrent users
had yet to launched)
hitting backend from the load test script and re-ran the test only against Sotchijunior
handle at least twice the load it could handle in the first test (the first test was 7,500
concurrent users and the second test showed it could handle 20,000 concurrent users)
As a result of testing with Load Impact
means all the content was delivered in plain text rather than Gzipped. Which made it
much more bandwidth intense for the communication between the Varnish and the CDN
between test iterations because they were able to keep and reuse the tests scripts
created with Load Impact team
Because of our hard work, the resounding success of the project and MTGx being great partners, ComputerWeekly recognized the effort as the Best Private Sector Project of the Year in its annual European User Awards. Click the award banner above to read more about what into the project.
