Sysctl settings?

What are some good /etc/sysctl.conf settings to consider when using ES?

  1. I don't set recycle or reuse
  2. tcp_fin_timeout to 15.
  3. swappiness to 0
  4. net.core.somaxconn=1024
  5. vm.max_map_count=262144
  6. Turn off ipv6 - et.ipv6.conf.all.disable_ipv6=1 and net.ipv6.conf.default.disable_ipv6=1
  7. fs.file-max=65536
