call stack does not add up to 100%

using dotTrace 4.0.1

 

best illustrated with a screenshot:

I have opened the method (SetView) in a new Tab, where the time taken is 8,705ms....

 

The method consists of 29% of ToArray( ) (which is a linq query) which takes 2,587 ms

 

What happened to the other 71%?

 

Cheers

Wal

Re: call stack does not add up to 100%

Hello Wallace

     Sorry for delayed response! Usually such result means that the SetView function spends the rest of the time (100%-29.72%) doing something else (e.g. not calling other functions and doing some math calculations for instance). If you have source code for that function, you can install dotTrace 4.5.1 and use the Line-by-line profiling feature to find out exactly what that function is doing. Thank you!

Re: call stack does not add up to 100%

Thanks, that makes sense now, was confusing at first.

 

I've since installed 4.5.1 and when analyzing profiles in the same way it no longer shows me the 'x calls' after the time taken for the method.

I've searched to turn this on but can't find it anywhere! How can i enable this please?

All good, I think, as I changed Profiling Type from 'Sample' to 'Tracing' and the call count returned.
