I posted about my mbuf leak problem earlier, but I thought I'd chime in again.
For those without uptimes, the mbuf usage depends on the uptime of the system and is pretty meaningless if you just restarted. Uptime: 1:30AM up 8 days, 5:12, 0 users, load averages: 0.13, 0.11, 0.08 Netstat -m: 12549 mbufs in use: 12545 mbufs allocated to data 4 mbufs allocated to socket names and addresses 2706/2716/15000 mbuf clusters in use (current/peak/max) 8576 Kbytes allocated to network (99% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines dmesg | grep rl: rl0 at pci1 dev 13 function 0 "Realtek 8139" rev 0x10: irq 9, address 00:e0:4c:e4:f1:5d rlphy0 at rl0 phy 0: RTL internal PHY rl1 at pci1 dev 14 function 0 "D-Link Systems 530TX+" rev 0x10: irq 3, address 00:50:ba:55:10:f1 rlphy1 at rl1 phy 0: RTL internal PHY Though, I don't get such horrible performance consistently (but there's always a leak). Note that in thise case kern.maxclusters was increased to 15000 for testing purposes. -Stefan
