There is an instrumenting (function-accurate) profiler for MS VC 7.1 and higher called MicroProfiler. <a href="http://visualstudiogallery.msdn.microsoft.com/133d5764-b32b-4ec9-8ee8-5546eca64584" rel="noreferrer">You can get it here (x64)</a> or <a href="http://visualstudiogallery.msdn.microsoft.com/800cc437-8cb9-463f-9382-26bedff7cdf0" rel="noreferrer">here (x86)</a>. It doesn't require any modifications or additions to your code and is able of displaying function statistics with callers and callees in real-time without the need of closing application/stopping the profiling process.

It integrates with VisualStudio, so you can easily enable/disable profiling for a project. It is also possible to install it on the clean machine, it only needs the symbol information be located along with the executable being profiled.

This tool is useful when statistical approximation from sampling profilers like Very Sleepy isn't sufficient.

Rough comparison shows, that it beats AQTime (when it is invoked in instrumenting, function-level run). The following program (full optimization, inlining disabled) runs three times faster with micro-profiler displaying results in real-time, than with AQTime simply collecting stats:

<pre><code>void f()
{
 srand(time(0));

 vector&lt;double&gt; v(300000);

 generate_n(v.begin(), v.size(), &amp;random);
 sort(v.begin(), v.end());
 sort(v.rbegin(), v.rend());
 sort(v.begin(), v.end());
 sort(v.rbegin(), v.rend());
}
</code></pre>

I highly recommend <a href="https://msdn.microsoft.com/en-us/library/hh162945.aspx" rel="nofollow">Windows Performance Toolkit (WPT)</a> or XPERF

The command line xperf command line tool records Event Tracing for Windows (ETW) logs that can be analyzed using the GUI xperfview tool.

Using <a href="http://blogs.msdn.com/b/pigscanfly/archive/2009/08/06/stack-walking-in-xperf.aspx" rel="nofollow">stacktrace command line arguement</a> has proven to be an invaluable tool for my company as it profiles and troubleshoots bottlenecks. One of the most compelling things is that the WPT can be installed in any environment even on the venerable Windows XP.

On Windows 8 the Windows Performance Analyzer takes xperf to an even higher level.

The hard numbers and stats provided in ETW logs are unparalleled in detail except for visual studio profiler (2010/2012) which is also great but not free AFAIK.

If you have never used xperf...you do not know what you are missing

You can use EmbeddedProfiler, it's free for both Linux and Windwos.

The profiler is intrusive (by functionality) but it doens't require any code modifications. Just add a specific compiler flag (-finstrument-functios for gcc/MinGW or /GH for MSVC) and link the profiler's library. It can provide you a full call tree or just a funciton list. It has it's own analyzer GUI.
