Scarroll has posted up some FAQs to answer some common questions that we are asked about the profiler.

 

Profiling FAQ #1: Why doesn't my Sampling Call Tree look like my Instrumentation Call Tree

 

Profiling FAQ #2: Why am I seeing functions from DLLs I didn't instrument in my Function view?

 

Profiling FAQ #3: How do -exclude and -include on vsinstr differ from -start / -suspend / -resume, etc.

 

Profiling FAQ #4: The top sampled function is [ntdll.dll], now what do I do?!
