XPerf uses ETW (Event Tracing for Windows) and is very low overhead, requiring only about 1500-2000 clock cycles per log. As an example, 20,000 calls per second is less than 2% CPU on a 2.0 GHz processor. While the data collection is running, the XPerf tools are not even loaded - the kernel itself is collecting the data.

The WPA Heap Analysis tool provides a comprehensive view of process heap behavior by producing graphs, summary tables and text based reports. WPA is based on Event Tracing for Windows (ETW). ETW is an Application Programming Interface that provides a mechanism to trace and log user and kernel mode events in a non-intrusive manner.

xperf (part of Windows Performance Analysis Toolkit) is very helpful in tracking memory usage with its heap analysis. However, my app uses a custom allocator -- it grabs chunks via VirtualAlloc directly and manages its own heap.

For those of you new to this, Performance Analyzer (aka xperfview) is the tool we use to analyze XPERF traces. It is installed with the Windows Performance Toolkit which is a part of the Windows SDK. See the previous link for more information.
Heap Snapshots–Tracing All Heap Allocations - Random …

The call stacks are stored in memory (thus increasing the memory footprint of the process being investigated) and can be dumped to an ETW trace file (.etl file) whenever desired – thus giving you a snapshot of the heap. This trace can be explored using Windows Performance Analyzer (WPA) with all of the power of its summary tables.

This tool needs it off in order to provide correct stack traces when a heap event occurs. So with that, I compile the code, and navigate to the directory where my binary (test_leak.exe) resides. I then created a batch script (which I call xperf_run.bat) that contains the following commands: Code Snippet @echo off
