Sender: owner-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk On a 2.1.7 machine "netstat -m" shows: 103 mbufs in use: 66 mbufs allocated to data 25 mbufs allocated to packet headers 8 mbufs allocated to protocol control blocks 4 mbufs allocated to socket names and addresses 65/118 mbuf clusters in use 248 Kbytes allocated to network (57% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines I have 256 users defined in the kernel so I would have expected to see (512 + 256 * 16) = 4608 mbuf clusters. Yes? I am reading this totally wrong? For an machine to have heavy hits and about 200 virtual domains what should my network buffers look like? Any help or wooden sticks are appriciated. -David Langford langfod@dihelix.com
