Hi,
at the moment we have the default configuration, beside the increase of
net.inet.ip.ifq.maxlen to 500 (I trust OpenBSD programmers more than I
trust myself about tuning).
I haven't had yet the opportunity to upgrade it to -current, I'll do in the
next few days.
Just a small punctualization about the pps, I have 22-24k in total, 10-12k
per card (internet facing and LAN facing)
Thanks again
Alessandro
