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

I am running RHEL5.2, but am not having anywhere near the latency you are.
The only apparent difference between our output is that I am on Xymon
4.3.0-0.beta2. I am also going over a gigabit network, but my DNS
resolution time never crawls above the microseconds all that much. Your OP
states that sometimes it takes up to 20 seconds to get resolution, and I'm
wondering if that isn't where you need to concentrate your efforts?
As much as I hate to suggest such a thing because of other potential bugs,
could you gain any benefit from having nscd running on the Xymon host only?

Hello again
Is there really no other option to speed up the ping test, maybe by using
multiple instance of fping/hobbitping. A collegue has the same issue on a
Hobbitserver running on HPUX.
I am running Redhat EL.

My experience with "hobbitping", is that it is just slower. You are
better off downloading and installing "fping". Once you do this,
you
will need to rebuild hobbit and select fping in the build process.
Instead of rebuilding hobbit, you can change FPING in hobbitserver.cfg
to
"/path/to/fping -Ae " or similar.
sorry for the delay. I just tried fping. But the turnaround time is
exactly the same, no benefit. Any other ideas?
