| 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.
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.
