Hidden latency in the Linux network stack

It seems like they are using a non-standard netstat switch:

  $ netstat -ep4ln --udp

Is that '4' a typo or something?

It's present in my netstat, from `net-tools 2.10-alpha`. Man page says it's shorthand for `--protocol=inet` (as opposed to `inet6`) which shows only IPv4 sockets.

It means only list ipv4 sockets. It's pretty standard across many command line network tools.
