We are using the default rules in the C code. flow generation is: src.ip.min 192.168.18.1 src.ip.max 192.168.18.90 src.ip.inc 1 Also, Please let us know the topology that you are using. > > > > > > > > > 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 ? > > > I'm sorry I can't tell you what's arm64 platform I tested on.
