Tested LPM with sudo ./examples/l3fwd/build/l3fwd -l 9,10 --master-lcore 9 -- -p 0x1 --config="(0,0,10)" Tested EM with sudo ./examples/l3fwd/build/l3fwd -l 9,10 --master-lcore 9 -- -p 0x1 --config="(0,0,10)" -E > My testing shows that EM case is much better, while LPM is almost the > same as before. Could you please tell on which arm64 processor/platform you tested. Also how much was the percentage increase in performance for EM ? > Thanks! > Jianbo
