Probably pertinent that I'm running knife as a user with an
auto.home-mounted NFS home directory, though I generally don't run
knife from within said NFS home.

With nsswitch.conf having "automount: sss files":

$ time knife node list > /dev/null
knife node list > /dev/null  5.37s user 2.11s system 12% cpu 59.150 total

and with "automount: files":

$ time knife node list > /dev/null
knife node list > /dev/null  4.28s user 1.80s system 82% cpu 7.393 total

Cheers,

John
