Load Testing

We understand the application performance with a large number of real users. We use different types of load and performance testing tools that help to analyze the system behavior with peak usage before the issue impacts on the user.

What We Do:

Server response speed
Handling concurrent user session
Page load times
API testing & data processing capacity

Where It’s Implemented

Pre-launch checks
High traffic events or public launches
SaaS platform validation

Stress Testing

We test your application by pushing it beyond the limits and analyze how it behaves. With our stress testing services at Tabdelta, we make your system overloaded so as to detect the breaking points, issues in the performance & validate them.

Evaluate the stability of the application under high traffic, resource exhaustion and detect unexpected user behavior. Implementing these strategies, it helps us to identify the memory leaks, crashes and dependencies that are seen during the stress on the system. Analyzing each issue in depth, we help strengthen the performance, improving faults detected and delivering a stable user experience under different stress scenarios.

Spike Testing

In an application there are chances to get unexpected traffic surges. It may be due to sales, breaking news or any influencer shoots. During these conditions it is important to know how the user responds during this time period. Hence, with our spike testing services at Tabdelta we simulate these conditions and analyze the user behavior to detect if any issue is found.

We test by increasing and decreasing the load in different factors like caching, session handling, backend stability & auto-scaling. Implementing this, in our spike testing it helps to identify the errors, slowdown of system or crashes if any. With the spike system it makes your system ready that is a matter of concern.

Soak Testing (Endurance Testing)

It is important to perform reliable testing, as in some cases performance errors don’t appear immediately. They come up after a couple of hours or into continuous usage. With our soak testing at Tabdelta, we test the application under real-world workloads with extended periods and analyze the performance of the application.

With our soak testing services, we help to uncover hidden issues like memory leaks, database slowdown, reduction in response time etc. By validating these issues, we ensure that the system is stable, reliable & responsive. We monitor system health throughout the testing process, help in uptime expectation validation, resource utilization and unexpected failure. Implementing soak testing is not about just performing well, but it is more likely to be long lasting performance.

Volume Testing

With performance & load testing benefits, your application must also be compatible with the aspects of volume testing as well. With our volume testing services, we evaluate your system performance across large volumes of data in short timeframes. Our Quality assurance testing services help to uncover the issues without compromising the quality, speed, stability & accuracy of the system

We implement the real-data loads into the system that helps to assess the database performance, speed, storage handling, system response under heavy data conditions. This will help to detect issues related to slow queries, data processing and indexing issues if any. Our volume testing services ensure a smooth & consistent performance no matter how big is the dataset.
