Hi! There is any configuration on interface, kernel or sysctl.conf to tuning of network performance? We have Connect-X 40Gbps and 100Gbps but we guess we can have more performance, you know? Our VMs have a +- 1 or 2gigas (1500 MTU) of throughput on iperf test. ovirtmgmt has around 27 ~ 30Gbps (9000 MTU) of throughput on iperf test. We already use 9000 MTU in all network devices and ovirt's bonds. Tests were performed without concorrence workload. Cheers!
