I can say from personal experience that gethostbyaddr() and
gethostbyname() can seem almost randomly slow, depending on machine, OS,
software, who knows. I'm not smart enough to figure out the reason why
it can vary so much on machines with nearly the same configuration, but
I can tell you that it works perfectly fast most of the time. Then
there's that other 5% where something makes it slow as molasses.
I have two machines that are so similar it's not funny, but
gethostbyname() takes 1/10 s on one, and 5 s on the other. I have yet
to figure out what's the difference between them that causing this.
