I am monitoring a 1 GiB network, an as you can see in my previous post
host is a dual core, 10 GiB ram and 5 e1000 nics ...

sysctl.conf:

# set to at least 16MB for 10GE hosts
kern.ipc.maxsockbuf=16777216

# Size of the TCP transmit and receive buffer.
net.inet.tcp.sendspace=65536
net.inet.tcp.recvspace=131072

# Increase auto-tuning TCP step size of the TCP transmit and receive buffers.
net.inet.tcp.sendbuf_inc=16384
net.inet.tcp.recvbuf_inc=524288

# Increase send/receive buffer maximums to 16MB.
net.inet.tcp.sendbuf_max=16777216
net.inet.tcp.recvbuf_max=16777216

# Increase UDP packets options
net.inet.udp.maxdgram=57344
