Is there a= ny way to generate packets from pktgen at 118 Mpps ? What is the command line for Pktgen? Using a single CPU you should be able to generate about 21Mpps, which tells= me the configuration is not correct. Pktgen needs N number of TX and RX cores to generate more traffic, plus the= packets need to be spread across the cores using RSS. This means pktgen ne= eds to be setup to generate packets with the 5 tuple difference to get all = of the cores to receive the packets. I need to know the command line and the configuration of the machine to hel= p. >=20 > --=20 >=20 > Thanks, > Shailja >=20 Regards, Keith
