How can you identify and eliminate performance hotspots in an informatics system?

2 How to measure performance?

Performance is a measure of how well an informatics system meets its functional and non-functional requirements, such as speed, accuracy, availability, and security. Performance can be evaluated using various metrics, such as response time, throughput, latency, error rate, or resource utilization. To measure performance, you need to define realistic and relevant scenarios, collect and analyze data, and compare the results with the expected or desired outcomes. You can use tools such as benchmarking software, profiling tools, or monitoring systems to help you measure performance.

4 How to eliminate performance hotspots?

Eliminating performance hotspots can be achieved by applying various optimization techniques, such as refactoring or rewriting the code or component to improve efficiency, readability, or maintainability. You can also tune or configure the parameters or settings of the code or component, such as memory allocation, cache size, concurrency level, or timeout value. Alternatively, you can replace or upgrade the code or component with alternative or newer technologies, frameworks, or libraries that offer better performance, compatibility, or functionality. Finally, you can scale or distribute the code or component with techniques like parallelism, load balancing, or cloud computing to increase the capacity, availability, and resilience of the informatics system.

5 How to prevent performance hotspots?

To prevent performance hotspots, it's important to adopt a proactive and continuous approach. This includes designing the informatics system with performance in mind, using principles such as modularity, simplicity, or testability. You should also review or test the informatics system regularly and monitor or audit it periodically. Additionally, it's beneficial to learn and improve your skills and knowledge on performance engineering by using resources such as books, courses, or blogs. Doing so will help detect and fix performance issues early and frequently while also tracking and reporting performance trends and anomalies.
