[Nfsen-discuss] when will nfsen's processing become too much?

[Maurizio M. <mau...@da...>]

Hi,
I'm observing that with 20 sources and 85 active profiles (around
15Mbytes of data per 5 min slot), if I don't do anything else with
nfsen, the cpu occupation of nfsen-run will raise (at almost 100%) at
HH:MM:30 (where MM is a multiple of 5) and drop again at very low levels
roughly after 3 minutes.
So, it looks that I still have a 2 min cushion before the system gets
instable...
I note that If I do something else that involves some heavy processing
(like looking for the 10 top src IP addresses over the past 24 hours on
the live profile...) nfsen-run's utilization stays almost continuously
high, even well after the other process has terminated. It may mean that
since nfsen's normal activities cannot terminate in the 5 min slot, due
to a competing process, they are nicely queued and terminate when there
is time later on.
Question: is this the way it works? If there is a "queue" of such
activities, how long can it be? and is there any way of realizing when
nfsen becomes instable, in this respect?
Thanks,
Maurizio
