Same here: "who" takes quite a bit of time to run because it seems to be trying to do a reverse DNS lookup. There is something strange here because I have a local named process that serves my IN-ADDR.ARPA zone so reverse lookups should be local and that should be pretty fast.
Anyone has any ideas of what's going on with "who"?
