With Puppet 3.8.7 you're hopefully running Puppet with Apache/Passenger.
If not, you have a puppetmaster (puppet master?) process that is single
threaded. You'll have to migrate to Passenger based setup. My guess is
that that you're running the standalone process since Passenger defaults
to 6 processes which should be able to serve 500 agents.

Thanks for your reply. I understand that i need to upgrade to puppet 4.
I'm just looking for similar options to optimize in 3 open source since
i have these in production and not easy to upgrade
Thanks & Regards,

Harish,
You are running puppet 3 open source and looking at directions for
puppet 4 enterprise edition. While some of the PE information will
surely apply to the open source edition, you should update to puppet
4 as puppet 3 is End of Support/Life. That upgrade alone should
improve performance significantly, at which time you can re-evaluate
performance issues.

Hi All,
Following is my puppet configuration details. Problem is that
puppet server and agent runs are going very slow at times and
restarting the server helps in production.
Puppet 3.8.7 (open source)
Facter 2.4.6
CentOS 7
Number of nodes: 500
Number of cores: 16
RAM: 32GB
I'm going through this puppet website
https://docs.puppet.com/pe/latest/config_monolithic.html#tuning-monolithic-installations-(reference)
<https://docs.puppet.com/pe/latest/config_monolithic.html#tuning-monolithic-installations-(reference)>
to fine tune my puppet.
Can someone help me in understand location of the files exactly
as i could not figure out *few (marked in Red)*. Please verify
my changes and let me know if there's anything wrong.
