The vm-to-vm bottleneck is typically in the hypervisor (vmware) and the switch (in this case it may be the linux bridge in centos). I am afraid just using netmap in the guest won't help you much in this respect. See our ANCS'13 paper http://info.iet.unipi.it/~luigi/papers/20130903-rizzo-ancs.pdf for what you can expect (look at the unmodified hypervisor/linux bridge case). This said, you can always use netmap (in emulated mode) on any network interface in the guest. cheers luigi > > Best Regards, > Pradosh > _______________________________________________ > freebsd-net@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org" -- -----------------------------------------+------------------------------- Prof. Luigi RIZZO, ri...@iet.unipi.it .
