Self Time is Zero?!?

Self Time is Zero?!?

hi,

I am tring to use Call Graph for some time measurement on functions of a program. The problem is that for some function the self time reported is exactly zero...I search in some post and i found some talking of euristic "self wait time" ( - i am not sure is the self time i am talking about: tell me if not! - )...I don't know if this is the cause of my problems, anyway I could accept that a self time of a function that really take a small % of total time of the entire program but I can't accept that a "big function" whit huge for loops inside have a self time of zero.

I hope in an hint to understand cause of the problem, thanks!

regards.
Matteo
