About Ram Lakshmanan
Ram Lakshmanan is the founder and architect of popular JVM diagnostic tools: GCeasy, fastThread, HeapHero, and yCrash. Ram has a deep focus on Java performance engineering & troubleshooting. He has helped several Fortune 500 companies including Apple, Visa, ServiceNow, and Workday to diagnose and resolve complex production issues.
On this blog, Ram shares his real-world experiences, engineering challenges, and lessons from building diagnostic tools used in some of the world’s most demanding production environments. His writing combines practical advice with hands-on examples in a simple, easy-to-understand language.
When developers are stuck with mysterious OutOfMemoryError, long GC pauses, or unresponsive applications, Ram’s tools and techniques provide the clarity they need.
Ram speaks at various developer conferences all over the world and conducts performance engineering workshops to share JVM tuning strategies and production troubleshooting techniques.

Application logs are crucial for engineers to troubleshoot production incidents, but manual inspection is often inefficient. The 'yCrash Log' tool utilizes AI and ML to analyze and structure unfiltered log data, identify errors, and provide solutions, improving incident response time and system reliability. It enhances traditional log management by automating root cause analysis.

Last week, I traveled from San Francisco to London for a keynote on Java performance issues, then visited NHS Scotland in Dundee. I appreciated their efficiency in adopting our yCrash tool. Productive meetings about .NET support led to planned releases in early 2026. Scotland's hospitality and culture left a lasting impression.

Troubleshooting on-premise application issues is complicated due to limited access to customer systems and reliance on their support staff for vital diagnostic data. Challenges include incomplete information, security concerns, miscommunication, and environmental instabilities. Implementing the yc-360 Script can streamline artifact collection, improving diagnosis and reducing resolution times.

The post addresses challenges faced in performance testing, including discrepancies between test and production environments, reliance on synthetic data, and the absence of long-running tests. To improve detection of performance issues, it suggests enhancing testing with Micro-Metrics, implementing chaos engineering, and recording production traffic for realistic simulations.

To accurately forecast production performance issues, validating Micro-Metrics is essential. Key best practices include enabling Garbage Collection Logs, triggering 'yc-360 Script' midway and at the end of tests, and utilizing self-trigger M3 mode for endurance tests. Comparing new and previous baseline incident reports helps identify performance degradation trends effectively.
