Did you use profilers during development? Which ones did you use, and what did you do?

Yes, I used profilers during embedded software development to optimize performance and identify bottlenecks.

For example, I used tools such as:

• gprof for analyzing function execution times in a Linux environment.
• Valgrind (Callgrind) for memory usage analysis and call profiling.

With the help of profilers, I identified functions with the longest execution times, optimized algorithms, and reduced resource consumption, which is critical for embedded systems with limited capabilities.
