A Scalable Solution for High-Concurrency Demands

The client is a large enterprise with a growing workforce spread across multiple regions. Their internal operations rely heavily on a corporate services application that provides centralized access to HR services, IT helpdesk, asset procurement, travel requests, and policy management. This application plays a critical role in supporting employee productivity and operational efficiency.

Given the application’s business-critical nature, the client needed confidence that the platform could perform reliably under increasing load without degradation. The client experienced growing performance concerns as user concurrency on the portal nearly doubled with business expansion. This increase led to:

• Noticeable delays in response times during peak usage
• Frequent timeout errors impacting user experience
• Concerns about meeting existing performance SLAs
• Uncertainty about the system’s ability to scale for future growth

To address these concerns, a structured and comprehensive performance testing approach was implemented. This included:

• Identifying high-usage business workflows such as leave requests, helpdesk ticketing, travel bookings, asset requisitions, and dashboard reporting
• Designing test scripts using LoadRunner to simulate up to 2,000 concurrent users across key workflows
• Collaborating with development and infrastructure teams to fine-tune SQL queries, optimize Java thread pools, and enhance middleware configurations

The testing initiative provided valuable insights and measurable improvements:

• Achieved sub-2-second response times for 95% of transactions with up to 1,800 concurrent users
• Identified and resolved a major bottleneck in the IT ticketing module that caused 5–7 second delays
• Conducted an 8-hour endurance test with less than a 1% error rate, ensuring stability under prolonged load
• Post-optimization, the system comfortably handled 2.5x the previous user load with no adverse impact on performance
