I have ported the kitrace performance-measurement tool to Linux 2.0
and made it available on the Web. Visit the kitrace Web page to get

What is kitrace? It's an interactive tool that allows you to
precisely measure kernel activity. For example, suppose your disk
driver isn't performing properly. Profiling may not help, because it
measures CPU time and averages over many executions of a function.
Stepping through with a debugger doesn't work because it destroys the
critical timing path. Kitrace lets you ask questions such as "how
much time elapses between when this disk request hits the queue and
when it is actually issued to the controller, and then how much longer
does it take before the data comes back?"

It's easy to install and easy to use. Try it, you'll like it.
