Have the option to Collapse different trees into one tree across different threads. about honest-profiler

[RichardWarburton]

I can't say which thread is more costly, since the threads are independent of each other from an execution profiling point of view.

I could keep track of thread states (for example whether you're running or sleeping) or how long a thread is running for. That would give you a view into where your CPU time is being spent. Would that help address this issue?

Apologies, I think I meant something slightly different which is to collapse the separate threads into 1 tree . Assuming that all samples have equal "cost" whether cpu or elapsed time it should work I think.

Afaik this is what all other profiling tools do that I have used to date whether instrumenting or sampling (doesn't make it correct though!), so would be interested if reporting per thread is more correct and therefore I need to adjust my expectations/experience.

This would be an option as the current per thread split also I am sure will have it's uses.

I'll open a separate enhancement for thread states :)

Ahh, I'm with you now! Collapsing into one tree is absolutely reasonable. I've had someone else request that. I'll rename this issue so to reflect that.
