Hi all,
I'm getting some packet loss on our firewall here (4.1 GENERIC), after
changing the old nic (msk0) we are still getting some packet loss but
very little.
Can be any improvement from changing the external nic from em2 to em0 in
our case? Can this packet loss be sure coming from cable problems or is
something with interrupts?
Changing from bsd.mp to bsd will improve?
Systat show me 14k interrupts in total, but the cpu is 99% idle.
Thanks in advance for all help, bellow is some info about the fw,
anything more just tell me.
netstat -nid:

em1 is the internal nic, em2 the external, this info is from about 10h
of uptime.
