Load Test

Load testing enables application performance to be scaled in terms of response time, resource usage level, hardware capacity, network capacity when the user load is at its maximum, so that it is determined under which conditions access to the application is sustainable and how many users can access the application simultaneously. When multiple users access the application, the load test identifies problems such as latency, page blocking in the system, and ensures that possible disruptions in the system are detected and prevented in advance.

The purpose of load testing is to maintain system reliability and performance, ensure the successful operation of system software, and ensure that the end user can take full advantage of the system.

load test;

  • response time for each transaction,
  • Performance of system components under various loads,
  • Network latency between client and server,
  • software design issues,
  • Server configuration issues such as web server, application server, database server,
  • It is involved in detecting hardware limitation problems such as memory congestion, network congestion, and whether the system needs tweaking or hardware and software changes are required to improve performance.


Load Test Stages

  • Determine test case
  • Determine load test operations
  • Prepare data for each transaction
  • Estimation of the number of users accessing the system
  • Determining connection speeds
  • Identification of different browsers and operating systems used by the user
  • Configuration of all servers
  • Test case execution and monitoring
  • Gathering and analyzing test results
  • Advice for correction
  • retest

Stress Test

Stress testing is designed to increase the number of simultaneous requests of a system after a point in which performance drops (even at a point of complete failure) to prepare for the unexpected, determine how far a given system can be pushed, and explore the outer limits of its performance capacity. If a load test peaks in concurrent users, the base load will continue to increase the load on the system until resources become overloaded. This is deliberately pushing the system into a fail state to see how the system handles itself and whether the system can perform a proper recovery. Thus, it enables the analysis of the risks at the breaking points and the minimization of the risks with fine tuning.


Frequently Asked Questions About Load Testing

Why Should I Perform a Load Test?

The purpose of a load test is to demonstrate that the expected volume of a system can be handled with minimal acceptable performance degradation. If a load test peaks in concurrent users, the base load will continue to increase the load on the system until resources become overloaded. This pushes the system into a possible failure state to see how the system is handling itself and whether the system can perform a proper recovery. To summarize in short articles; Load testing tests the reliability and performance of my system. Load Testing helps detect bottlenecks in the system under heavy user stress scenarios before they happen in a production environment. Load testing provides excellent protection against poor performance and offers complementary strategies for performance management and production environment monitoring.

What Strategies Are Used When Performing Load Testing?

There are many ways to do load testing. Here are a few examples for you to get an idea of: Manual Load Testing: This is one of the strategies to run load testing, but it does not produce repeatable results, cannot provide measurable stress levels in an application, and is very difficult to coordinate. In-house developed load testing tools: An organization that recognizes the importance of load testing can create its own tools to perform load testing. Open source load testing tools: There are several load testing tools available for free as open source. They may not be as sophisticated as their paid counterparts, but are the best choice if you're on a tight budget. Enterprise-class load testing tools: They often offer a Capture/Playback option. They support a large number of protocols. They can simulate an extremely large number of users.

What Information Will I Gain About My System As A Result Of The Load Test?

The load test allows you to see the variables listed below in case of abnormal use of your system. Response time for each operation Performance of system components under various loads Performance of database components under different loads Network latency between client and server Software design issues Web server, application server, database server etc. server configuration issues such as CPU maximization, memory limitations, network congestion etc. hardware limitation issues such as
