Performance Testing Services UK

The reliable and consistent performance of your business-critical applications is the key to success of your enterprise. However, performance problems within an application are often identified in live scenarios, which significantly damage your brand’s reputation. That is where formal web performance testing of the applications is necessary to ascertain application behaviour at peak performance and scalability levels.

TestingXperts helps in identifying bottlenecks, and predicting application behaviour and performance in a simulated, real-life environment, thus saving you from unpleasant events later, which frustrate customers and impact profitability. We ensure the application is responsive and reliable enough to respond to peak load days like a black Friday sale and can also scale to other future events like product release, acquisitions, new clients, regulatory changes and ongoing business growth. We also ensure the applications can meet any contractual obligations and SLAs for performance.

Performance testing Services

We offer load testing services for applications across domains and technologies, including web-based n-tier applications, client-server applications, SOA based solutions or COTS solutions. We have experience with all industry-leading monitoring and performance testing tools and expertise in end-to-end application performance testing, including network, database, hardware, etc.

We publish a detailed report for the application with response times, break-point, peak load, memory leaks, number of concurrent users, resource utilization, uptime, etc. We provide clear and actionable application tuning recommendations and help you implement those working closely with various IT teams in your enterprise.
