Hi,
while trying to find things in our puppet setup I could tune I had a look
into /var/lib/puppet/state/last_run_summary.yaml and saw the time consumed
by "config_retrieval" which is always around 11 sec.
> cat /var/lib/puppet/state/last_run_summary.yaml

- I
read about catalog caching and that it might take a while. So I inserted
the recommended extra bit of debug lines to find out how long catalog
caching takes and gave it a try...
> puppet agent --debug --no-daemonize --onetime

So catalog caching takes less than 2 sec. but there's something else
indicated by three lines starting with "###" that takes up a big part of
the 11 sec. Can you tell me what this is or how I can find it out?
Thanks in advance,
Your help is highly appreciated,
Christian
