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.
