Hi,
How do i profile a library which is dlopened from an executable.
The executable and the library are compiled with -g using gcc . Can
somone tell me tool that would profile it at runtime.
Regards,
Nik

While updating my port (math/slatec) to use
the new OPTIONS framework, I did some
experiments with the profiling library.
I don't know much about this, so what surprised me
is that the profiling library is smaller:

Also, the library compiled on amd64 has lots more

Forgot to meantion that the test is based on FreeBSD kernel 7.0 2000807
snapshot.
The kernel was compiled with a modified version of GENERIC configuration.
With SMP and PREEMPTION disabled and kernel profiling enabled.

Could we say that interrupt handlers consumed ~36% execution time?
Is this number too high? Is it possible that we abuse the use of critical
sections in kernel?
I think whether or not it is high depends on

spinlocks disable interrupts so the profiling interrupt is held off
from the
moment that the spinlock is entered to the moment it is exited, and all
of that time is attributed to spinlock_exit().
so that this tells you that 3% of your time is spent under spinlocks

Hi all.
What is the right way to measure wall-clock time in profiling on FreeBSD?
Standard profiling method in UNIX like 'gprof' measures CPU time, but
it doesn't always offer a good indication for tuning if application is
not CPU bound.
For example, the below simple program spend most
Hi,
I need to debug some software, written in Python (with threads), which uses
dynamically loadable modules, written in C.
FreeBSD version is 5.2.1-RC.
All Python modules are compiled with -g -pg, so is the python binary.
By default, -g -pg -pthread doesn't seem to link libc to Python
if there is a C++ friendly debug tool out there...
Thanks,

Hi,
Does anyone out there know a good C++ memory profiling/debugging tool for
FBSD? I'm looking for a tool like valgrind or purify. I grepped around

seem to be for C only (as they refer exclusively to malloc free).

I am looking to do profiling of one of my programs. I know about gprof and cachegrind
for linux but was wondering if there are other tools that are recommended to have or
to use instead. The test systems I have access to are Linux, FreeBSD, and some nice
Sun machines.
Thank you,

see my answer to your previous posting. mcount is a function

if i read the table correctly, .mcount is the guilty, isn't it?
i think mcount is used for profiling, so it doesn't count! see
