It is a router passing ISP traffic (lots of stuff, mostly port 80 and torrents....). dev in/out igb0 300Mbps/200Mbps igb1 400Mbps/100Mbps em0 40Mbps/4Mbps em1 100Mbps/400Mbps em2 150Mbps/50Mbps Rebooting 5 days ago with these tunings in loader.conf fixed the issue... Thanks for all the help, FreeBSD community! kern.ipc.nmbclusters=524288 hw.igb.rxd=4096 hw.igb.txd=4096 hw.em.rxd=4096 hw.em.txd=4096 Oh, and I ordered a motherboard with two ix and two igb devices on the motherboard. That will replace this slightly older router. http://www.supermicro.com/products/system/1U/1026/SYS-1026T-6RF_.cfm It is 1U and has room for 3 PCIe cards, whee! Rudy
