RE: CPW limit

[Joe Giusto <jgiusto@xxxxxxxxxxxxxx>]

Is there any way to set the timer interval manually?

It is not even that (in a sense). The timer issues an interrupt every so
often to signal to the operating system that it is time to give the CPU to
another job. Processing of interrupts is done by task(s) CFINTnn. These
tasks run all the time and perform necessary interrupt processing.
Processing an interrupt takes a certain (short) time, so you don't want
the timer to interrupt too often. If the system exceeds its CPW interactive
limit, the timer interval (inverse of how often the timer interrupts) is
just
set
to a very small value, forcing the machine to spend almost all its time
processing these interrupts and the system slows to a crawl. Later,
when interactive load decreases, the timer interval is increased again.
