Otherwise i work on Puppet optimizations and i have seen some
strange things too. I work on big catalog (more than 1000 resources)
and i want to reduce the application time (around 20 sec).
I have seen two kind of things:
- First, recent Puppet versions are slowest (see PuppetVersions.png
in attachment), mainly the last one: 2.7.12.
I can confirm that.
It's one of the reasons I'm still on 2.6 at a lot of places, as I have
a 10-20% catalog compilation time increase with 2.7. Even with a
master pre-2.7.12 (might have been 2.7.1 or so), which is what I
tested and I never read it got better, hence I never retested it.
- Second, ruby 1.9.3 is very slow compare to ruby EE (see
PuppetRuby.png in attachment). I think the problem come from the
yaml library: caching catalog is very slow.
It is interesting that 1.9 is slower.
But anyway I remember that caching the catalog (read serializing it as
yaml to disk) has been very slow for years and also known. It usually
makes the agent look like it's hanging. This especially happens on
huge catalogs - I have catalogs with up to 10k resources.
Having a puppet release focused on stability and performance would
really be appreciated. I think there could some room for improvements
at various places.
