He claims to have reduced the CPU usage by 80% and doubled network throughput (he expects more, but it was limited by memory bandwidth). The approach looks like it would work on FreeBSD as well. I spoke to him and he confirmed. He's currently trying to get the code released as open source, but in the meantime his slides are up on http://www.lemis.com/grog/Documentation/vj/. Yes, this is my web site. The conference organizers are going to put it up on their web site soon, but in the meantime he's asked me to put it were I can. Comments?
