(I keep playing the self-entertainer here, but it's OK)

I ran "time /usr/sbin/smokeping --debug" and got this:

.. alert compilation ...
Launched successfully
EchoPingHttp: probing 5 targets
FPing: probing 36 targets
EchoPingSmtp: probing 0 targets
DNS: probing 4 targets
EchoPingHttp: forks 5, rounds 1, timeout 90

EchoPingHttp: executing cmd /usr/bin/echoping -h / -n 20 ab7-intranet.charite.de

(lots of output, all probes work OK, no timeouts)

real    1m10.085s
user    0m11.200s
sys     0m2.640s

Why on earth 70s? Why aren't The DNS, EchoPingHttp, adn FPing probes
done in parallel? Is this a feature of the --debug mode?

Also, in the debug mode the FPing probes are not printed out. Why?
