ping test is too slow

[thorsten.erdmann at daimler.com]

Hi

for some time I am having problems with out ping test of hobbit. It runs 
longer that the time intervall. Is it possible to speed up the test? I 
don't want to make the intervall longer.
I am using the hobbitping. I tried doubling --max_pps from 50 to 100 with 
no effect. 

Most of the time the DNS-lookup eats up 20 seconds, but sometimes it is 
near zero! Why that? Most of my monitored system have a testip tag, so 
should not do any DNS lookup at all. But some WLAN accesspoints which are 
configured for using DHCP does not have the testip tag.

In the manpage of hobbitping I read something about a runtime of 18 
seconds for 1000 clients. Why it is so slow on my machine? It's a fast 
machine, Opteron with 1GBit network interface.

Here ist the output of bbtest:
