[Click] background processing?

[Beyers Cronje]

Hi Nick,

I dont think Click is ideal for asynchronous processing. As you know
standard Click runs in one thread, so basically you're left with Task/Timer.
You can try playing around with SMP Click and have your element scheduled on
it's own CPU, but I havent had much luck getting a stable SMP Click
installation. Maybe someone else can comment on their experiences with SMP
Click?

Stuff that might assist you:

ScheduleInfo http://www.read.cs.ucla.edu/click/elements/scheduleinfo - You
can ensure your task is scheduled less often than other tasks.

Possibly subscribe to a NotifierQueue and only schedule your task if the
upstream queue is empty, depending on your configuration this might indicate
when there are low traffic going through Click.

What type of processing do you want to do?

Regards

Beyers
