Had mediocre network performance and increased load with freebsd on VMs (kvm), while at the same time a linux one would saturate a whole link.

- cyphar 11y agoWhy are you trying to get network throughput on a VM? Of course it's going to be slow, but KVM probably has some passthrough optimisations for Linux guests.
- nl 11y agoBecause that's what software defined networking is (mostly) about. In the majority of cases it's used as a way to setup a network plane for virtualized hosts. Edit: See for example why VMWare bought Nicira: http://techcrunch.com/2012/07/23/vmware-buys-nicira-for-1-26-billion-and-gives-more-clues-about-cloud-strategy/ http://techcrunch.com/2012/07/23/vmware-buys-nicira-for-1-26...
- cyphar 11y agoI'm not a BSD guy, but I can still see it's a little unfair to compare the network throughputs of Linux and *BSD as guest VMs on a Linux host running KVM. You aren't going to get good throughout in that case without hardware passthrough (even then it's still bad). End of story.
