Hello, Robert. You wrote 19 августа 2011 г., 12:41:41:

Our network stack is actually pretty parallel as such things go, and there are a number of changes in FreeBSD 9.x that extend this work. Most of the performance work is being done on edge nodes rather than middle nodes -- i.e., maxing out multiple 10gbps links serving content, etc, rather than in routing configurations, though. We also have a strong and growing collection of 10gbps drivers. You'll find our drivers lifted for many other systems, including Solaris :-).

I need to bribe our admins (OPs) on my paid work to try FreeBSD instead of Solaris on new servers :) We are processing huge amount of multicast streams (up to 2.5-3Gbit/s with 500-1000 bytes packets) and have difficulties not to lose any packets on Solaris :) They tried Linux without success, but FreeBSD is unknown to them.

One problem for FreeBSD is that our applications are Java-based... Problems are not in Java, but in Intel drivers (igb / ixgb in FreeBSD terms), which sometimes lose packets with "buffer is not available" diagnostics when consumer is heavily-multithreaded.
