[hobbit] Antwort: [hobbit] Antwort: Re: [hobbit] ping test is too slow

[Patrick Nixon]

I'll agree with jerald on this one.

 If your DNS is not resolving properly, it can increase your ping
times as well, because ping does a DNS lookup as well when it
executes.

 Check your DNS server/records, walk through your bb-hosts file to
determine if something is timing out/not resolving, and I suspect
you'll find the culprit
