So is this a problem with the physical switch (we need a better switch) or with the configuration of the switch (we need to configure the switch or configure the os to work with the switch)?
You may want to look if you are dropping packets somewhere. You can look at the packet count on the sender and receiver interfaces and see if they match (within epsilon). You can also look if your switch supports hardware flow control, it would prevent packet loss is the receiver is slower than the sender, but even slow/busy machines should be able to receive 1 Gb/s these days.
What does ethtool -S ethX says on the worse sender/receiver pair ? Patrick
