I've just completed upgrading my FreeNAS box to 11.3 and reset the config to default. I read over at servethehome that FreeNAS would soon come out of the box with the correct tunables for 10Gb networking. Is this the case with 11.3 or should I be adding something along the lines of:

  • kern.ipc.maxsockbuf = 16777216
  • net.inet.ip.intr_queue_maxlen = 2048
  • net.inet.tcp.recvbuf_inc = 524288
  • net.inet.tcp.recvbuf_max = 16777216
  • net.inet.tcp.recvspace = 4194304
  • net.inet.tcp.sendbuf_inc = 32768
  • net.inet.tcp.sendbuf_max = 16777216
  • net.inet.tcp.sendspace = 2097152
  • net.route.netisr_maxqlen = 2048

Any news here?
How can I check what's configured as default? If I look at /etc/sysctl.conf I do not see any of these parameters...

I assume like in many UNIX and Linux style operating systems the config files are only filled with data when the default values have to overwritten.
I would be interested in that too!

Run sysctl -a to see the current defaults.
