The Finnish Kennel Club is a trusted expert organisation, interests organisation and opinion leader in the canine sector, with more than 146,000 members and 2,000 member clubs. The organization's main event is the Dog Fair Finland and it is by far the Finland's biggest dog event with over 16,000 dogs participating.
During the previous years, the event site experienced serious slow-downs in their site before and during the event due to massive amount of users looking for ticket sales and photos. For the 2017 event they wanted to pro-actively ensure that the site could handle the load. The hosting setup is a custom tailored solution with several application servers running behind a load balancer. All application servers serve the traffic from a shared NFS file storage backed by MySQL database.
Together with the site administrators Supervisor conducted a test where TrueVisitor was used to generate simulated browsing traffic. For this case there was no custom scripted actions, just browsing as the expected traffic pattern for the site has a large spread among different pages. Despite of the custom hosting setup, the testing caused several page loads to return errors for the users with just a few hundred users browsing the site. The administrators quickly identified the bottleneck to be a misconfiguration in the load balancer's simultanous connection limit. Once this limit was raised the site performed well with over 1000 concurrent users. While running the peak number of users, the total network utilization was over 600 megabits per second due to the TrueVistor's unique ability to load all images from image galleries as a real browser would.
As a result of pro-active testing, the site performed well under the peak traffic as expected.
