So, I have CCR1009-7G-1C-1S+PC and happy with it in general. My setup is 2 WAN 1Gb uplinks on eth1/eth2 and a LAN bridge on other ports. My PC has Intel 1Gb NIC attached to eth6 on the rounter. The router is configured for load balance/failover both WANs (mangle, conn/routing marks) - works like a charm. So I've added another Intel NIC and attached in to eth7 in hope I can double my bandwidth (server side multi-connection load). This isn't working for some reason, the bridge speed is capped at 1Gbps although each channel including WANs demonstrates true 1Gb performance individually. The router's CPU is at 40% max.
See the screenshot, please, for better visualization. Is something wrong with my thinking? What's weird is the bridge capped speed is always summary of Tx+Rx although all the connections are full duplex.
