This result can't satisfy me, so I add another network adapter, and
try the code blow:

//////
socket1 = socket(AF_INET, SOCK_DGRAM, .....)
socket2 = socket(AF_INET, SOCK_DGRAM, .....)
bind socket1.network adapter1...
bind socket2 network adapter2
time = time(NULL);
while (1)
{
sendto(socket1, "", 1, 0, dstaddr1, addrlen);
sendto(socket2, "", 1, 0, dstaddr2, addrlen);
count += 2;
}
time = time(NULL) - time;
avg = count / time;

But I get the result is also 75000 packet per second, WHY?


It look like that when send a packet to bond dev, bond use current
slave and send packet, then change current slave to next. What is the
essence different between the bond and my code (use two network
adapters)?

Any suggestions?

I am not really sure, but I think the bind to an adapter under linux only chooses the source ip, not really the adapter used to send the packets.

Did you check that the two destination ips have routes through different interfaces, and not go out through the same one?

(You should even be able to verify this with tcpdump, if you get packets on one interface and nothing on the second)
