Use netstat -m to chek the current configuration/load.
It's something like this:
----
191/8272/65536 mbufs in use (current/peak/max):
186 mbufs allocated to data
5 mbufs allocated to packet headers
170/8128/16384 mbuf clusters in use (current/peak/max)
^^^^^^^^^^^^^^
18324 Kbytes allocated to network (37% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
----
You can modify the number of mbufs with sysctl variable
kern.ipc.nmbclusters.
Usually setting this on /boot/loader.conf
ex.:
kern.ipc.nmbclusters=16384
Check also tuning(7) ;)
