bug: Total Total time in the analysis tree is overstated

[petehale]

Summary

When I am looking at the Analyze tab I see the times associated with the debug run; Self Time and Total Time.
Total time represents the total time spent in each of the table items.

The Total line is summing the total time for each entry in the two time columns, leaving the sum of Total Time overstated.

Steps To Reproduce

1. Run a a apex debug session
2. Download log
3. Open Analyze tab

Expected result

I believe the Total Total Time should be removed, as it is meaning less.

Actual result

Overstated Total Time sum

Right now we have it setup to just sum all the totals, which leads to double counting.
It would be more accurate to just show the largest number. That would work as long as only have one EXECUTION_STARTED and have not filtered out that event type.

A better approach would be to collect the stacks and only sum the unique entries e.g
If we have an analysis like this

methodA: 5s
methodB: 3s
methodC: 2s

Sibling Methods
The three methods are at the same level directly called from EXECUTION_STARTED.
All 3 should be summed as they are in different stacks.

Total: 10s

Child Methods

methodB is a child of methodA and methodC is a sibling of methodA.
we first add methodA to the total but the total for methodB has already been accounted by including methodA so we skip it and any other children of methodA.
methodC is in a unique stack and needs to be added to the total.

Total: 7s

I will see when we can fit this in.
