> Hi,
> we have recently worked on a project, called netmap, which lets
> FreeBSD send/receive packets at line rate even at 10 Gbit/s with
> very low CPU overhead: one core at 1.33 GHz does 14.88 Mpps with a
> modified ixgbe driver, which gives plenty of CPU cycles to handle
> multiple interface and/or do useful work (packet forwarding, analysis, etc.)
> 
> You can find full documentation and source code and even a picobsd image at

> 
> The system uses memory mapped packet buffers to reduce the cost of
> data movements, but this would not be enough to make it useful or
> novel.  Netmap uses many other small but important tricks to make
> the system fast, safe and easy to use, and support transmission,
> reception, and communication with the host stack.

> You can see full details in  documentation at the above link.

> Feedback welcome.
