How can I profile the performance of my C++ application?
You can use tools like gprof, Valgrind, or Visual Studio's built-in profiler to analyze performance.
What are the key metrics I should look for when profiling?
Focus on CPU usage, memory allocation, function call frequency, and execution time.
Can you explain how to use gprof for profiling?
Sure! Compile your program with the -pg flag, run it, and then analyze the output file 'gmon.out' using gprof.
Are there any best practices for optimizing performance based on profiling results?
