Why Load Testing is Critical for iGaming Platforms
The traffic for iGaming platforms is anything but predictable. A major sporting event or the release of a popular slot machine can bring thousands of users to a platform within a matter of minutes. Should the platform’s underlying infrastructure not be prepared for such traffic, the platform can suffer from slow response times, failed registrations, and downtime for users.
Load testing has thus become an essential part of the engineering of iGaming platforms. Engineers can simulate traffic of various intensities to test the performance of a platform prior to users creating any registration or traffic for it. This test can run for publishers, affiliate marketers, operators, and software providers to ensure their platforms run consistently during peak periods of demand.
What is Load Testing?
Load testing is a process that simulates the expected levels of traffic for a website. Engineers can use the simulation to understand how a website will perform with high numbers of concurrent users.
Some of the scenarios that engineers can simulate during load testing include:
High numbers of website visitors
High volumes of affiliate clicks
Simultaneous player registrations
Reporting system requests
API traffic
Testing these scenarios prior to the platform receiving actual traffic allows engineers to prepare for the demands of the users.
Why Does Performance Matter?
Performance for the iGaming industry is vital for a number of reasons. If a platform has high response times for users, it can result in a number of negative outcomes for platform operators. For instance:
Lower conversion rates
Higher bounce rates
Abandoned registrations
Reduced player satisfaction
Lost affiliate revenue
Performance is, therefore, not just an engineering metric for iGaming platforms, but also a business metric.
Simulate Real User Behavior
Load tests should simulate the behavior of the website’s actual users. Many simulations for load testing include the following:
Visits to the homepage
Visits to casino review pages
Clicks on affiliate links
Registrations for new players
Logins to the player dashboard
API requests
Testing scenarios that mirror the behavior of real users ensures that engineers gain the most valuable insights from the testing process.
Identify Infrastructure Bottlenecks
Another vital purpose of load testing is for engineers to identify any infrastructure bottlenecks for their platforms. Engineers can identify bottlenecks in areas like:
Database queries
API endpoints
Server resources
Network bandwidth
Background jobs
By identifying these bottlenecks during the testing phase, engineers can optimize the platform prior to the introduction of live traffic.
Validate Auto-Scaling
Many iGaming platforms employ auto-scaling software to adjust their cloud infrastructure according to traffic demands. Engineers use load testing to validate that this auto-scaling software is properly set up by simulating situations in which servers should be launched, traffic distributed, and resources scaled back.
Including auto-scaling in load testing ensures that the software is reliable, and that it does not increase infrastructure costs due to overprovisioning of resources.
Protect Affiliate Traffic
Traffic from affiliate links is subject to spikes during major marketing campaigns. However, engineers must ensure that the affiliate traffic system can handle high levels of traffic. Load testing ensures that affiliate systems can handle high traffic volumes with accuracy in recording the clicks, fast redirects, and availability of reporting tools.
Improving the reliability of affiliate tracking ensures that the trust between these organizations is maintained.
Improve API Reliability
APIs are essential for most platform functions. During load testing, engineers can simulate high traffic volumes for these APIs to assess their performance. Engineers can measure metrics such as:
Response time
Throughput
Error rate
Request latency
Availability
improving API reliability improves each function and service that relies upon the API.
Test Reporting Systems
Reporting dashboards receive high traffic volumes during major campaigns or sporting events. Engineers test reporting systems to ensure that they can maintain fast loading times for dashboards, allow users to filter data, provide analytics, and provide export capabilities for reports.
Ensuring that the reporting system performs well during peak times is essential for the business users of the software.
Measure Recovery Time
Measuring the recovery time for a platform is another purpose of load testing. When a platform experiences high traffic volumes, it is likely that it will experience crashes and downtime. During load testing, engineers assess recovery times for the platform to measure the speed with which the software can recover from crashes and maintain its operations.
Including recovery time as a measurement during load testing allows engineers to ensure that the platform can recover quickly following any crashes.
Include Mobile Traffic
A percentage of all traffic for iGaming websites comes from mobile devices. Therefore, engineers must include mobile traffic during load tests. Mobile traffic can be simulated by testing on mobile browsers, mobile operating systems, different data connection speeds, and tablet devices.
Including mobile traffic in load testing ensures that the website continues to offer users the same experience on mobile devices as on desktop computers.
Monitor During Every Test
During every load test, engineers must monitor a variety of metrics for the software and servers that handle the traffic. These metrics can include:
CPU utilization
Memory utilization
Database performance
Network traffic
Error frequency
Cache performance
These metrics allow engineers to gain a complete understanding of the software’s performance during peak traffic and determine where the infrastructure can be optimized.
Automate Performance Testing
Performance testing should be a part of every software release cycle for iGaming platforms. By automating the performance testing process, developers can establish performance benchmarks for the software and track these benchmarks throughout the software’s development cycle.
Automating performance tests allows engineers to rapidly respond to performance issues and continuously improve the software.
AI Is Enhancing Load Testing
Artificial intelligence is playing an increasing role in load testing software. AI features that enhance load testing include the ability for the software to:
Simulate traffic based on traffic predictions
Generate realistic traffic volumes
Detect unusual website behavior
Recommend infrastructure changes
Forecast auto-scaling requirements
These features enhance the engineers’ abilities to prepare the platform for traffic.
Common Mistakes in Load Testing
There are a number of mistakes that many organizations make in reducing the value of load testing software. Some of the common mistakes include:
Simulating unrealistic traffic
Ignoring API performance during testing
Limiting load testing to the website itself
Failing to monitor the infrastructure during testing
Ignoring recovery time testing
Comprehensive load testing can provide engineers with far more valuable information.
Best Practices in Load Testing
To maximize the value of load testing software for the iGaming industry, engineers should:
test the platform regularly
simulate traffic with the same behavior as real users
include mobile traffic in testing simulations
monitor the software and all infrastructure layers
validate the auto-scaling function
measure the recovery time for the software
automate load testing processes
document the performance benchmarks of the software
By following these best practices, engineers can increase the usefulness of the software and extract the most information from it.
The Future of Performance Engineering
Performance engineering and load testing software are increasing in value and importance for the iGaming industry. Many of the developments in the future of the industry will focus on improving performance engineering. Some of the future developments in this area will include:
AI-generated traffic simulations
Continuously monitoring software performance
Autonomous software infrastructure tuning
predictive performance tools
real-time performance optimization software
These innovations will allow iGaming software platforms to remain reliable in the face of growing user demands.
Final Thoughts
Load testing is one of the most valuable engineering practices for modern iGaming platforms. By simulating the traffic that will fall on production platforms before it arrives, engineers can identify any weaknesses in the infrastructure and work to optimize the platform for better performance.
For publishers, affiliate marketers, operators, and software providers in the iGaming industry, load testing ensures that platforms provide users with high levels of performance and reliability. These platforms are essential to driving traffic to publishers and operators and generating revenues for all organizations involved. Thus, load testing is an investment that the iGaming industry will continue to value into the future.
