What you see are two mystic things:
It seems that hobbit resolves all clients via DNS: =20
# hostnames resolved : 40
Why that, I gave all names and it's corresponding IPs at the bb-hosts=20
file?
The IP's in the bb-hosts file are mostly there for backward compatibility
with Big Brother. Hobbit will do a DNS lookup to determine the IP-address,
and only if this fails will it fall back to using the IP listed in bb-hosts.
If you want to skip the DNS lookup, add a "testip" to the host lines in
bb-hosts, or a "--dns=ip" option to the bbtest-net command in hobbitlaunch.cfg.
I want to add about 400 network switches which should only do a ping test=20
and I fear that this would extremely increase the runtime of the bbtest.
What can I do to decrease the runtime?
Drop the DNS lookups of all hosts (see above), or run a local caching DNS
server on the Hobbit server. Hobbit does send a lot of DNS requests very
quickly, and I know from personal experience that some DNS servers have
problems with this.
