Hello!
I have LVS system with two Six-Core CPUs and 2x 10G Intel NICs. Intel ixgbe
driver creates 24 tx/rx queues.
While testing with iperf tool traffic was distributing among 24 RX queues.
But with LVS traffic distributed only among 16 RX queues.
How to direct traffic to all 24 rx queues?
HW configuration:
HP ProLiant DL360 G7, 2x Intel Six-Core E5645, 16GB RAM, 2x Intel
Corporation 82599EB 10-Gigabit NICs
Linux Kernel 2.6.38.8
Some ethtool output
# ethtool -i eth0
driver: ixgbe
version: 3.2.9-k2
firmware-version: 0.9-3

# ethtool -k eth0
