Issue #17820 has been updated by Per Cederqvist.
My problem was a file {} stanza that tried to ensure that all files
under/var/lib/puppet/reports were owned by puppet:puppet. See issue #17828.
----------------------------------------
Bug #17820: eval_generate is needlessly slow
https://projects.puppetlabs.com/issues/17820#change-77549
Author: Per Cederqvist
Status: In Topic Branch Pending Review
Priority: Normal
Assignee:
Category: performance
Target version: 2.7.21
Affected Puppet version: 2.7.9
Keywords:
Branch: https://github.com/puppetlabs/puppet/pull/1293
By changing a single line in eval_generate in lib/puppet/transaction.rb I
managed to speed up "puppet agent --test" from 4494 to 593 seconds. The code
should produce the same result, but avoids allocating so many hashes.
Here is the diff. If you prefer, I can create a Git branch et c, but I hope it
isn't necessary for such a simple fix.
I'm also attaching the output from two ruby-prof runs, in call graph format:
before and after the change.
(593 seconds is still too much. I suspect I might be submitting a new bug
report in the not too distant future. :-) Still, this change should be a
speedup for everybody, and it shouldn't hurt anybody.)
