warning for short profiling duration (low number of samples) #130

Open ceeaspb opened 8 years ago

Split out from #126, if a profiling duration is too short even if the expected number of samples according to a sample schedule is achieved, not enough enough samples may have been collected to provide a repeatable profile under sustained workload.

eg. there could be high run to run variance if repeated enough times.
