The getdelays utility helps pin-point possible resource shortages when
running an application. The SLES10 kernel includes patches to implement
delay accounting, which measures the time a process spends waiting for
disk I/O, swap I/O and CPU time slices. For example, if an application
is running rather slowly, delay accounting can tell you where it spends
all its time.

For instance, when the CPU delay is high, this means the
application is competing with other proces for run time,
but is losing quite often.

High memory delays mean that the sum of applications running on this
system need more physical memory than is available, and are swapping
quite a lot.

In order to enable delay accounting, you need to specify "delayacct"
on the kernel command line when booting the system.

For additional information, please see the getdelays(1)
manual page.
