I ask this question about a week ago, but I may have asked on the wrong mailing list.
I am trying to compare the performance of the bridge application included in netmap with that of linux kernel bridge application. I have noticed that the performance of netmap bridge application is significantly lower than that of the linux kernel bridge. I am not sure that I am using the netmap bridge application correctly. Looking to be pointed in the right direction. I am running the experiment on a single box using two network namespaces. Here is an overview of my setup: -Linux Kernel 3.14.28 with netmap module loaded -two network namespaces: h0, h1 -two veth pairs: veth0, veth1, veth2, veth3 -one bridge implementation: linux kernel bridge or netmap bridge -Each veth pair is terminated on a network namespace and the bridge implementation that I am testing I am running iperf from network namespace h0 to h1. With the linux kernel bridge iperf is reporting a bandwidth of 24.1 Gbps With the netmap bridge application iperf is reporting a bandwidth of 118Mbps The command I am using to setup the netmap bridge application is: ./bridge -i netmap:veth1 -i netmap:veth3 The result of the experiment (24.1Gbps vs 118Mbps) seems off, no? Also which branch/tag of this repository https://code.google.com/p/netmap/ should I be using for the latest linux version of netmap?
