We provide our performance testing services at key stages of the SDLC to ensure your system’s flawless operation

## Questions that application performance testing helps you answer

We provide comprehensive performance testing services, backed by over 20 years of experience with reviewing systems ranging from enterprise banking platforms to high-traffic mobile games. Our specialists help companies prevent system flaws and unpredicted post-release expenses and ensure they get answers to the following questions:

We help ensure spotless performance for your software

## a1qa is here to help

Whether you develop websites, desktop solutions, or mobile applications, our QA team can help your software engineers ensure flawless performance of the developed product.

### Services we provide:

![](https://www.a1qa.com/wp-content/uploads/2023/10/icon-37-4.svg)

### Load testing

Providing software load performance testing services, we determine whether the system can cope with the expected target load for an extended period of time. For instance, we helped confirm that shoppable [video platform could](https://www.a1qa.com/portfolio/thorough-testing-of-ml-driven-software/) reliably handle **up to 100,000 concurrent users,** allowing ML-driven product recognition and interactive on-player purchase cards to function seamlessly without interruption.

![](https://www.a1qa.com/wp-content/uploads/2020/11/icon-5-9.svg)

### Scalability testing

We validate software effectiveness during processing power increase and architectural changes. For instance, we verified that a [mobile casino game](https://www.a1qa.com/portfolio/a1qa-tunes-performance-of-a-mobile-game-for-a-global-provider/) could **seamlessly handle growing user loads on Android and iOS,** using Google Cloud autoscaling to add server instances as demand rose, while providing recommendations on the number of instances required.

![](https://www.a1qa.com/wp-content/uploads/2020/11/icon-33-1.svg)

### Stress testing

We evaluate software performance under extreme loads to identify the upper limits of its capacity. For example, we ensured that online store ran smoothly during peak sales events like **[Black Friday](https://www.a1qa.com/portfolio/a1qa-provides-extensive-qa-support-to-a-large-us-based-manufacturer-of-home-appliances/) or Cyber Monday** by detecting bottlenecks early and recommending optimizations, thus decreasing page load time **by 30%.**

![](https://www.a1qa.com/wp-content/uploads/2020/10/icon-44-9.svg)

### Volume testing

We measure software productivity when storing and processing accumulating volumes of data. In particular, our QA specialists can validate that a banking system can reliably handle **years of transaction history** without slowing down queries or compromising data integrity.

![](https://www.a1qa.com/wp-content/uploads/2020/11/icon-31-5.svg)

### Stability testing

We perform testing activities lasting for about 72 hours to evaluate the system’s operability under a mid-level load. To illustrate, we ran **cloud-based pest control software** continuously while simulating hundreds of [concurrent users](https://www.a1qa.com/portfolio/a1qa-com-portfolio-meticulous-qa-for-pest-control-firm/) accessing services, updating sales records, and managing logistics and monitoring performance metrics in Grafana and CloudWatch to identify issues and recommend optimizations.

![](https://www.a1qa.com/wp-content/uploads/2020/11/icon-8-7.svg)

### Configuration testing

We verify performance under various software and hardware configurations. For instance, we tested **a multinational news portal** during its [migration](https://www.a1qa.com/portfolio/all-inclusive-quality-assurance-service-package-delivered-to-global-media-company-with-focus-on-shift-left-testing/) from a third-party system to an in-house framework, analyzing how the website responded to **different server setups and scaling scenarios** to ensure stable performance for readers across devices, regions, and subscription features.

## Business benefits of software performance testing

## Client-side performance testing: a1qa specialty

Our R&D lab has come up with a proprietary solution to the issues typically affecting customer experience, such as cluttered interfaces, long response times, and poor performance overall. We call it client-side performance testing. This tailored approach delivers measurable improvements in speed and efficiency, namely:

![](https://www.a1qa.com/wp-content/uploads/2020/11/icon-28-9.svg)

Optimized page loading

![](https://www.a1qa.com/wp-content/uploads/2020/11/icon-29-1.svg)

Accurate caching

![](https://www.a1qa.com/wp-content/uploads/2020/11/icon-29-2.svg)

Reduced server response times

![](https://www.a1qa.com/wp-content/uploads/2020/11/icon-29-3.svg)

No heavy-weight elements

## How a client-side performance testing solution helps

In addition to server-side testing, we conduct client-side performance testing which allows measuring the load and render time for an HTML page and detect defects that slow down the page load. Our QA team has extensive experience in automating client-side checks within any testing environment.

![Developer working at multi-monitor workstation with code, representing software performance testing services](https://www.a1qa.com/wp-content/uploads/2020/10/img-client-side-testing-1.webp)

### With client-side performance testing, customer experience can be improved through:

-   Measuring the loading speed of specific pages from different geographical regions, if required
-   Assessing the app speed after system updates
-   Identifying defects that slow down page loading and rendering
-   Detecting heavy-weight elements to optimize the amount of stored and transmitted data

## Choose your testing scenario

We offer several service packages tailored to companies’ particular needs:

## Frequently asked questions

Typical performance testing services include load tests to measure normal usage demands, stress tests to find breaking points, scalability tests to see how well the system scales up and down, and client-side checks to improve user-facing features’ performance. Each approach helps ensure your software stays high-performing and reliable.

Yes, since by detecting and resolving software performance issues early, you can avoid expensive fixes down the road. A well-tested system also reduces the risk of unexpected downtime or overpaying for cloud resources, which saves money in the long run.

Fast, stable software keeps users happy and helps you maintain your reputation as a software product provider. Performance testing helps ensure your system can handle real-world traffic, handle spikes, and avoid crashes or slowdowns, which makes it a key step to delivering a smooth, reliable software product.

Performance testing should begin at the onset of the software creation process rather than just prior to the solution’s launch. This allows for detection of processing delays, inefficient scripts, and architectural gaps while they are still easy and inexpensive to fix.

The span of a performance testing project depends on the system’s architecture, scale, and functionality. Preliminary setup and scoping are done quickly, but developing scripts, executing tests, and interpreting metrics take longer.

We evaluate response time, requests per second, CPU, memory, and disk space usage, error rate, virtual users, transactions per second, network, and many others. These insights are shared alongside expert analysis and recommendations, offering a clear view of software behavior in various scenarios and assisting with targeted improvements.

Sure. We use a distributed network of load agents to recreate traffic from different parts of the world, letting us evaluate the impact of distance on latency, speed, and system health, ensuring your software remains fast and reliable for users everywhere.

We run spike tests, stress tests, and burst scenarios to replicate rapid surges or inconsistent usage habits. Our specialists also examine past or projected activity logs (when possible) to simulate close-to-life traffic swings and track how the software scales and stabilizes.

Client-side performance testing focuses on evaluating how software behaves on a person’s devices, whereas standard performance verifications measure server and API efficiency under load. Specifically, this type of testing gauges page load time, rendering speed, resource loading, and responsiveness, while standard performance testing focuses on server response times, throughput, and system scalability.

We leverage dedicated test beds or staging areas that mimic the live production environment. This allows for recreating realistic usage patterns without interfering with your current users. If we need to test in the production environment, we use limited traffic, off-peak scheduling, and continuous monitoring to keep the risks low.
