on dprofpp

[j]

hi all,

I am using dprofpp to profile my code. I have some questions on that:

1) Will the subroutine shown overlap with each other ? say :
9 % Foo1::Foo2::Request
8 % Foo1::Foo2::subRequest

but actually Foo1::Foo2::Request is calling Foo1::Foo2::subRequest. How
could I make it clear in that presentation ?

2) I profiled that LWP::UserAgent::Begin is always very large in CPU user
time. Is there any way to reduce that ?

3) Is there any tools for profiling which is preferably free ?

Thanks.
