Dear all,

Do you have an idea about the best settings I can use to increase
point-to-point throughput? With a 4 NIC teaming in balance-rr I cannot
achieve more bandwidth than if I use a 2 NIC team, sometimes it is even
worst. I have tested the connections by using netperf and a practical test
using rsync.

I currently have 2 PE2950, each one has an Intel 4 Port Gigabit card.
Installation is RHEL 5. Latest igb driver installed manually and GRO is off.
MTU is 9000.

For each machine, all four cables are connected to a PowerConnect 6248
switch.

Do you know what special settings should I use in the switch to increase the
speed. Currently I have increased the MTU for the ports but no LAGs
configured for this and it seems to work without trouble.

I also noticed that although the Transmit load in the interfaces is evenly
distributed, the receive is not.

Now reading it seems that I need to create a LAG and configure STP and
Bridge Multicast support.

Any ideas would be welcomed.

Thanks,

Francisco
