Hello,
Ok. Can you help me with something else ? Right now, at a rate of 1.3~1.4 Mpps I am having about 4~5% of packet loss, I wonder if I use my application wth a 10G NIC, will it not be able to cope with more than 1.4 Mpps ? Because by seeing a packet loss I got a little afraid of it.

You can look at programmers guide section 24 "Power Management" and "L3 Forwarding with Power Management Sample Application" in Sample Applications User Guide. Regards, Vladimir. 2014-04-01 9:24 GMT+04:00 Fred Pedrisa <fredhps10 at hotmail.com>: Hi, Why by default L2FWD saturate both cores ? I mean, it seems it keeps wasting cycles due to the infinite loop placed there to check the queues. Which would be the way to improve this and make it to become more efficient ? Sincerely, Fred
