NIC has four ports each with a capacity of 1 Gbps. After configuring the switch, I am able to get approximately 3.5 Gbps with round-robin, TLB and ALB and 3Gbps with XOR. However when I remove bonding and give each port (eth0, eth1, eth2, eth3) a different IP address and mac address and send data from 4 different client machines to different ports e.g first machine ---> eth0, second machine --->eth1, third machine ---->eth2 and fourth machine---->eth3. With this configuration, how much bandwith should I get? I think I should get 4 Gbps because I am using 4 different IP address they should respond individually. However I am getting 1Gbps total. Please correct if I am wrong and if I should get 4 Gbps then I do I need to change something in configuration?
