Some people have asked for a “wall clock time” column in the sampling profiler report. Unfortunately, the actual time spent in a function cannot be reliably deduced from the collected data.
Because of this, the number of hits does not represent the wall clock time spent in the function. A function that is blocked waiting on a resource, waiting for a different process (e.g. calling a remote process), or just calling an expensive system call, may get a number of hits that is not proportional to the time spent in the function.
