Searching for a good "CPU TIME" python profiler (not wall time)

[alonn]

That produces flamegraphs and allows annotating a specific function only (e.g not the whole django app) 

from what I saw, line profiler and cprofile measure wall time. e.g time from start of function to the end, and specifically here I need to find out the CPU killer (which isn't where the most time is spent)

I'd be glad for recommendations

I need to find out the CPU killer (which isn't where the most time is spent)

I don't understand what is CPU killer. 

https://jiffyclub.github.io/snakeviz/ allows you to filter by function name.

And maybe py-spy will help?
