I have set up NIC bonding on a computer. 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?
