KERNEL PROFILING

HI ALL,
I am trying to profile the linux kernel. Can any one suggest an easy way
to do. Like, I wanted to see how much TCP is using CPU, how much of CPU is used in memcpy, etc. Can any one please suggest me.

Thanking You
Shesha

Start with the file linux/Documentation/basic_profiling.txt (it's in Linux 2.5.66-or-so or later).

It explains how to use oprofile and readprofile.

You can read about oprofile at http://oprofile.sourceforge.net/ .

You can read about basic in-kernel profiling using /proc/profile and readprofile via 'man readprofile'. It's simple to use.
