   That's really cool and directly affects my current work project. I'm
developing (have developed, actually) a multi-threaded, 5000+ member VoIP/SIP
conferencing server called Nconnect. It a primarily UDP application running
on FreeBSD 7. This generates and receives about 250,000 UDP packets a second,
with 200 byte packets, resulting in about 400Mbps of traffic in each
direction. The current bottleneck is the kernel UDP processing. It should
be possible to scale to 10000+ members if kernel UDP processing had optimal
concurrency.
   Anyway, thumbs up (and not for the middle-eastern meaning :-)) - I'm
looking forward to the MFC.
