I was researching a slow call in one of our apps and found a PurePath where the Method Execution Time in the PurePath Tree did not match that same method Execution Time in the Methods View for the same PurePath. The method in the Tree View shows 34 seconds where in the Methods view it shows 182 milliseconds where there is actually 34 seconds of DB time within that method. Every other time I've drilled in from a PurePath into Methods and vice versa it always matche. Why wouldn't it in this case??? See below
There is a measure for this. Create a measure in your system profile and look at Server Side Performance -> Transaction based Measures -> Methods -> Time. Note that if you wanted the execution time of just that method and no children you would use the "Exec Time" measure in the same category.
Hope that helps,
