OK. The last point could slightly help in reducing the number of calls to
kqueue and aggregate more events at once. But FreeBSD's kqueue is really
fast so that should not change much. You really need to be able to pin the
processes to certain CPUs, as well as the interrupts. Unfortunately I

This is managed by FreeBSD, it currently have multiple queues and irq

(As far I know).
JFYI: you can assign IRQs to CPUs via cpuset -x irq
(I can’t tell you if it is “like on linux” or not though).

So yes, a lot of recv/send calls as you said before.

Hi,
Yes, this is why I was speaking with Jeff about this.
Because I suppose that these processes have a default loop, that uses a
certain amount of CPU (kQueue implementation)
Its not busy polling, if thats what you are referring to. CPU usage should
be low with kqueue (because its fully

Hi,
Yes, the current version (for my usage) is really stable.
However, you are right, because too many processes, will create too many
threads, assuming I have just 16 Physical Cores...
Do you believe on a good CPU usage decrease, by switching to one process
only ?
I can't guarantee it,
12.45, sometimes going up to 16.00 +/-
