How to get peak memory usage?

Hi,

For getting the peak memory usage I tried out using the API GetProcessMemoryInfo() and the structure PROCESS_MEMORY_COUNTERS::PeakWorkingSetSize.

But I am getting different values for the same process when executed twice. So I am not very sure whether this truly represents the peak memory usage.

Any suggestion or ideas are welcome.

When testing anything on a computer, you have to take a running average. Peak memory usage will change based on what resources are available at the time. If you are truly interested, I recommend using the Red-Gate Tool Ants Performance Profiler.[^] I use that in house to look at my code. It does memory along with testing the execution times of all lines of code. It quickly showed me places where we needed to improve our code.

I don't work for Red-Gate, I just like their tools. Hope this helps you out!
