Hi, I don't even really follow the development anymore let alone develop, but I just wanted to make sure you'd seen the recent discussion of Van Jacobson's net channels. The talk was presented at Linux.conf.au and covered moving the key parts of the network stack into userspace to avoid lock contention. This design seems like the BeOS way, it gives much higher throughput and allows for way better scalability on N-way systems. There is certainly merit in going with what works and hase been done before. But it just seems like you have no legacy problems to trying this fresh new idea. Linux can't do it since it needs to stay compatible with netfilter/iptables/... A good first read on the subject is here http://lwn.net/Articles/169961/ Tom Young
