Chipsets and drivers matter a lot in the 1G+ range. I've had pretty good luck with the Intel stuff because they offload a lot in hardware and make open drivers available to the community. On Thu, Dec 26, 2013 at 7:48 PM, Olivier Cochard-Labbé <olivier@cochard.me>wrote:

Any benchmarks of freebsd vs openbsd vs present day linux kern?
Hi,
Here are my own benchs using smallest packet size (sorry no Linux): http://dev.bsdrp.net/benchs/BSD.network.performance.TenGig.png
My conclusion: building a line-rate gigabit router (or a few rules ipfw firewall) is possible on commodity server without problem with FreeBSD. Building a 10gigabit router (this mean routing about 14Mpps) will be more complex in present day. Note: The packet generator used was the high-perf netmap pkg-gen, allowing me to generate about 13Mpps on this same hardware (under FreeBSD), but I'm not aware of forwarding tools that use netmap: There are only packet generator and capture tools available.
