Does anyone have an ideas, hints, or even vague notions of why
Puppet's service execution might be somehow different? I'm certainly
out of ideas to try.

I'd like to use /etc/hosts to avoid the DNS propagation delays.

a hostname and pass that IP to the hosts type? Somet

Dooh, thank you. I wish I could remove the previous email to prevent

Well, yes, they are indeed 64 bit (x86_64). But that doesn't
distinguish them from the quicker ones. They are all running

I haven't read the article, but from this piece of information I'm
_highly_ skeptical of the results having much to do with puppet
itself.

Puppet's performance and scaling problems
The only explanation that I can find that explains the problems that I and a
few other user have been having is that 0.25.x adds a security feature that
makes it needed during the creation of client certificates. (Either that or
during the signing or retrieval of the certificates.) It could be

I tried, but all I could get it to do was add the entries to the end of

I was thinking about doing so to add/delete several commands to an
administrator group as part of setting up an apache/tomcat/whatever
instance, but cant figure out how to do it, for reasons similar to this

So, some of us would like to be able to set the nice value on puppetd.
However, we don't want all of our services (and some of our execs)
re-niced.
Would it be feasible/practical to have the ability to set the nice
value explicitly on Service and Exec calls?
Thanks,

Hi,
I'm new to puppet (doing an assesment of the puppet features

Out of curiosity, which part of puppet is causing this load? If it's

Hello
When testing puppet scalability, we noticed that one bottleneck is CPU usage on
puppetmaster node.
To scale up the number of concurrent puppet clients running in the same time, we tweaked our puppet configuration in
order to reduce puppetmaster work, mainly reducing its CPU work, and so s

Currently Foreman does not auto assign classes to your nodes (Except if you

Both of them can't connet server, because we are't using DNS.

Without wanting to appear flippant, perhaps I want a floating car :)
