Loadtests – one of the fundamental tools in Web Performance Management
|
Apica LoadTest© reveals how public web site performs under stress and heavy traffic. Apica LoadTest© creates a realistic load by creating so called synthetic users from a defined test platform, which generates users and user scenarios as they are created by end users.
Apica LoadTest© uses a diligently defined and controlled environment for its load tests, consisting of different test centers with normalized load servers and a close supervision of environment and servers. Apica has access to more than 20 different servers in the Nordic countries and Europe and can generate a total load of over 10,000 concurrent users per minute, which equals 600,000 page views per hour, to a web site/day.

Set your own test profile
Apica LoadTest is unique in the market today, as it will allow customers to perform tests of true internet load on-demand, anytime and with the following functionality
- Choose, Sweden, Nordics, Europe or USA as a starting point for tests, to simulate different traffic patterns depending the structure of your own business.
- Loadtests of single pages and/or transactions, which can be defined in several steps and thus simulating business critical scenarios
- Support for dynamical content, such as search words, users and URLs
- Study performance of full pages as well as individual objects and thus discover bottlenecks or defaulting objects.
- Evaluate response time, availability performance stability between various ISP:s in different locations
Apica LoadTest© can be scheduled to be run during low traffic, i e ”dark hours”, alternatively with certain intervals, to serve as ”wake up calls” before actual users visits the site. Tests can be performed at any volume of traffic you wish and testing any key scenarios and/or functionality you wish.
Typical questions to be answered by an Apica LoadTest:
1 – How many users can we handle?
Key performance issues for business critical web applications are:
- How will the application perform when the number of users increases?
- Which response times will we have under maximum load?
In principle, all applications has the following performance behavior under load:
- At first, no significant increase in response time can be noticed
- Later, at a first “knee” of the graph, response times are starting to increase significantly – either in a linear or an exponential fashion. At this point the web server has reached its maximum capacity. Any additional users will only lead to longer response times and in some cases eventually to a total collapse of the application or that individual sessions are unanswered.
2 – How does the load curve look?
Apica LoadTest© will - as a result of a performed load test - deliver a detailed curve of the load, which clearly will show where the maximum performance is and what behavior the application will show around and beyond maximum load.
What is your performance graph like?
- How many users can your web application handle with sustained response time?
- What happens at a peak? Can the application handle occasional peaks?
3 – What load test do we need?
To be able to perform a a realistic loadtest planning, some fundamental data is necessary. An Apica LoadTest© will supply you with a good foundation for analyzing and following the impact of changes in hardware and software, i e at a virtualization or when releasing new versions of a software or application.
4 – What variations in traffic patterns can we cope with?
A sudden increase of traffic can happen as a result of many things; seasonal variations, DDOS attacks, general news, changes in the on-line environment, etc.
Apica LoadTest focuses on helping businesses and organizations to simulate seasonal variations such as Christmas seasonal online shopping, year-end effects, time limits for public on-line services, etc. Seasonal peaks varies with different businesses segments and types of organizations, but almost all have significant seasonal variations and peaks which also come with substantial value.
It is important that many business critical transactions can be performed in a short time frame. A great advantage with Apica LoadTest© is that recorded transaction scenarios can be used at a later stage to be able to follow and verify response times on a real time basis with Apica Availability, Apicas service for response time and up time measuring and monitoring.
Apica LoadTest as a service – A simple and quick solution
Apica’s loadtests and stress tests will give the answer to how much the application can handle at a significant traffic load, but also the answer to how the response time curve will look under a significant load increase. Traditionally, it has been complicated and therefore also expensive and time consuming to set up load tests of external and internal web sites over the internet and intranets. Apica LoadTest© is a quick and cost efficient services to use.
Apica delivers complete scenario tests, which will identify a production-/acceptance environment’s
- response time and default situations
- outline of the load curve
- adequate response- and alarm actions
Optimization of application performance
Loadtests are a important part when optimizing an application’s performance. A load test will ascertain that the application delivers stable, low and consistent response times over the full load spectrum. A load test is often – and should always be – the last step before a new or changed application is launched live.
The constantly changing and competitive web environment means constant change; of both operating systems and application layers. Both small and more significant changes in the operational infrastructure will jeopardize stability, with subsequent risks for downtime and/or performance problems.
To be able to detect individual problems which are not visible when performing internal, component or segment based tests, complex web applications and/or environments has to be tested from the user interface perspective: many performance problems today are often found in the configuration and the interaction between components.
By using Apica LoadTest's external load tests, the risk for unexpected distortion can be minimized. Excellent usability and the controlled environment will guarantee that identical tests can be performed over time, which makes comparing different tests easier.
Load tests which generates a load equivalent to traffic peaks for a web application will give an IT-manager comfort that these applications will perform well under periods of high pressure, or a decision making tool for building out loadtest to avoid costly and damaging crashes during seasonal and/or campaign traffic peaks.
