Project will be going to Beta in a week''s time. Crossbow will provide options to dladm command by which you can specify CPUs that a NIC should use to handle incoming traffic. The command will re-target the interrupt to one of the specified CPUs if more than one CPU is specified and the network load will be distributed among the other CPUs. -krgopi> Thanks. > > --- > Rodrick R.
