I’m using MFC in Visual Studios. I wondered what the best way to measure the speed/efficiency of an operation (eg Function A vs Function B) working in this specific IDE. Can this be done with breakpoints?

No, use
QueryPerformanceCounter(docs) for accurate measurements of speed. From comments from @MadKeithV, this seems to not be a good solution, as CPU speed scaling (reducing CPU speed according to current load) may change CPU tick length.Using a good profiler is a better idea, or just use
clock_tto measure.
