Hi,
I've just upgraded my local test master to 3.0 and wanted to share the ups
and downs.
* The upgrade went as smooth as could be expected: config.ru migration
tripped me up, but was documented.
* There were still unexpected differences in behaviour which were not
warned by 2.7. In my case I was inspecting variables in templates and in
3.0 scope.lookupvar now returns nil in some cases.
* Compilation times for my biggest testcase (~3000 collected resources)
dropped from ~110 seconds to ~70 seconds.
* Agent runtime sadly did not improve beyond this:

Well, apparently caching catalog is taking around 38 seconds, which
should be compared to what it took beforehand (you didn't paste your
previours catalog run for this host). This time is not accounted in the
catalog run itself, and I believe that's where the agent is now faster,
so I don't expect you'll see large catalog run time decrease.
This catalog run time is mostly driven by the resource you're managing,
and there's no magical bullet in Puppet 3.0 that automatically make
calls to the package manager, files, users or services dramatically
faster...
The run with 2.7.19 takes around ten minutes wallclock time. 3.0.1 takes
around nine minutes wallclock for a complete "puppet agent --test". The
difference is approximately the time saved on master compiling the
catalog. I'm not concerned about the two minutes spent actually managing
3000 resources (~0.04s per resource). I'm concerned about the other
seven minutes overhead.

Is this with traditional stored configs or with PuppetDB?
PuppetDB. The compilation took *MUCH* longer with mysql.
