I have two 4.6 servers, and one 4.5 firewall with mostly two type cards: Intel Pro 10/100 and Intelinet 10/100 (rtl8139C). Two segments of network, one is on Cisco Catalyst 2900 second built on ATI 8224 10/100 switch. On both solutions transfers are around 8-9 MB/s betwen FBSD-> FSDB, FBSD->Linux, Linux-FBSD. All of those cards work on 100 Mbps/Full Duplex mode.. I didn't notice any strange behavior on FreeBSD, only Linux show messeges like: eth0: card reports no resources. eth0: card reports no resources. but there is no slow down because of this message...
