Hi, Linux has a feature called NAPI, which amongst other things has this Interrupt initiated polling mode. Whilst the network traffic is quiet the network interfaces use interrupts, however as soon as the load becomes higher polling kicks in and stays like that until the load drops again.
I know that FreeBSD can do interrupts or polling, but not together. I think that that NAPI pretty neat as it provides the benefits of both interrupts and polling, namely low CPU load (when the network is not busy), and high performance. I was wondering if anyone has considered this approach in FreeBSD? If not why not? Is there some reason why the binary FreeBSD approach is better? Or is it just that no one has dedicated the time and effort to implement this feature?
