In a previous project, we faced performance issues during peak usage times. I used BlazeMeter to identify the bottlenecks. By simulating high traffic with JMeter scripts and monitoring server responses in real-time, I pinpointed the problem areas. The database queries were taking longer than expected due to inefficient indexing. After optimizing the indexes, I reran the tests on BlazeMeter. The response time improved significantly, resolving our bottleneck issue.
