Speed, Efficiency, Success: How Indium’s Performance Testing Expertise Helped a Government Organization Slash Response Time by 50%
Client Overview
The client is a government rail transport organization overseeing large-scale operations, including passenger services and coach maintenance management. Their operations are powered by an integrated management system, which provides real-time insights into operational status, ensuring accurate and consistent reporting for streamlined decision-making.
On the Fast Track: The Performance Bottlenecks in Rail Operations
The client’s core application comprised a web-based Centralized Portal, Asset Management Application, and BI reports essential for railway operations. Over 500 users rely on it daily for 50+ critical transactions, including managing railway coach details and tracking maintenance status. However, heavy usage strained performance, leading to long wait times, delays, and service disruptions directly impacting government operations.
The existing application's performance testing focused on three key areas: scalability, capacity, and bandwidth.
User Load & Scalability Testing
The application and its modules were tested to handle 100% user load with 300 users.
It was validated to scale up to 200% user load while maintaining performance.
Bandwidth & Network Simulation
WAN testing was conducted using 2Mbps bandwidth to replicate real-world network conditions.
SLA Compliance & Response Time Monitoring
Server response times were continuously monitored to ensure adherence to SLA requirements.
80% of user transactions were targeted to be completed within 3 seconds.
Overall response time was maintained below 8 seconds to meet performance expectations.
Operational Challenges
One of the key challenges was ensuring real-time performance under operational SLAs
To resolve the aforementioned challenges, the client sought Performance Assessment and Capacity Planning, including load testing to ensure high availability, scalability, and minimal latency under peak user loads. The application also needed to comply with SLA-defined performance benchmarks for seamless operations.
Rail Operations, Reimagined: Performance Testing that Delivered Speed & Scalability
To implement this, a business case analysis was conducted to identify the system’s most time-consuming transactions and queries. Performance assessment metrics were aligned with overall application response expectations to ensure accuracy and efficiency.
A key area of focus was scalability. Load distribution percentages were calculated for different application modules and user types, followed by load testing with 500 concurrent users to evaluate system resilience.
During testing, a scalability issue was identified in the BI reports’ module. To address this, Indium provided strategic recommendations for optimizing performance and ensuring seamless scalability.
The recommendations included:
Optimizing SQL queries to enhance database performance
Applying filters to minimize data queue size and improve processing efficiency.
Creating indexes on ETL tables to accelerate data retrieval.
Increasing the JVM heap size on the corresponding server to enhance memory management.
Capacity Planning Analysis
-
Database Efficiency
The database hit ratio was calculated and found to be above 98%, indicating efficient handling of system requests.
-
Memory Optimization
Heap memory spikes were detected in a specific application server, and the issue was escalated to the development team for further investigation and resolution.
-
Query Performance Tuning
The most time-consuming Asset Management queries were analyzed, and insights were shared with the relevant team to optimize SQL queries for improved performance.
Bandwidth Testing Analysis
-
Network Performance Evaluation
Bandwidth testing was conducted using threshold values of 1-2 Mbps to assess the application's performance under varying network conditions.
-
Module-Specific Testing
Each application module was tested individually, and concurrent user capacity was determined and reported based on the specified test scenarios.
-
Stability & Response Assessment:
User network monitoring tools were utilized to evaluate bandwidth, measuring the application's response time and overall stability.
