FreeBSD router problems

Hi! I have a problem with my FreeBSD router, I can't get more than 1 Gbps throught it, but I have 2 Gbps LAGG on it. There are only 27 IPFW rules (NAT+Shaping). IPoE only. lagg0 (VLAN's + shaping) - two 'igb' adapters lagg1 (NAT, tso if off) - two 'em' adapters I tried to switch off dummynet,
