It is my experience that you do not need a kernel rebuild unless you
want profiling information inside the kernel, otherwise it'll just lump
all kernel calls into the same group. In that same vein, you may want
to see if you can get a debug-version of glibc in case you need
profiling information inside of glibc. It depends largely on the
application, but with a "debug kernel" and a debug version of glibc,
you can see exactly what your particular program is calling, or whether
an inordinate amount of time is spent in the system (ie, page faults)
or in libc (ie, memcpy()).
