Hi,
On a freebsd 9.3 system:
> vmstat -z | egrep "mbuf_cluster|ITEM" | column -t
ITEM SIZE LIMIT USED FREE REQ FAIL SLEEP
mbuf_cluster: 2048, 10284, 1152, 56, 4237, 0, 0
> netstat -mb | grep "mbuf clusters in use"
512/696/1208/10284 mbuf clusters in use (current/cache/total/max)
one can see that:
current + cache == total == USED + FREE
but the current/cache values as reported by netstat
are very different form USED/FREE values reported by vmstat, so
they should have different meaning.
Ny question is: what us the exact meaning of USED/FREE and
current/cache values? Is there any relationship between them?
