FAQ
Hi,
I recently updated from puppet 3.1.1 to 3.2.1 and noticed quite a bit of
increased load on the puppetmaster machine. I'm using
the Apache/passenger/rack way of puppetmastering.
Main symptom is: higher load on puppetmaster machine (8 cores):

    - 3.1.1: around 4
    - 3.2.1: around 9-10

Any idea why there's more load on the machine with 3.2.1?

    You have to be a little bit more specific. Is load only CPU related, or
    I/O? Also, what do the log say? 3.2 pushes lots of notices about syntax
    obsolescence in the logs...

    Forgot to enable email notification here. Decided to go back to 3.1.1 a
    week ago. Will upgrade again to provide more specific load information. Thx!

    Two load situations, one pretty high, one relatively low. Usually it's
    somewhere in between these.

    Forgot to say this explicitly: config_retrieval times (guess this includes
    catlog compilation) on the agents explode.
