I ran a haproxy(nbproc=6) on freebsd 10-beta2, each frontend bind to a
socket and share the same backend. Context switch normally 60k+. But the load
and throughput is confused me, in the past days I ran a haproxy instance
(nbproc=1), it can handle up to 500Mbps traffic .

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

This is managed by FreeBSD, it currently have multiple queues and irq
balance with msix.

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

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 ?
