Adam,
100% CPU on Windows nodes has always been the norm for us. We tried beefing up our systems with a minimum of two cores, but we found that the client runs still had significant impact on the systems, even with very basic cookbooks. We ended up moving
away from running chef-client on regular intervals on Windows since the impact to our production environment was too great.
Chef 0.10.8 was the last version we checked CPU usage on. We will be rolling out 10.14.2 on the Windows side soon.

Hi Adam,
only one simple cookbook:
http://community.opscode.com/cookbooks/getting-started ( 0.4.0)
node.json:
"run_list": [ "getting-started" ]

What are the cookbooks/run-list? This is very odd.
Adam
Hi,
I'm currently testing chef (chef-solo) on windows to convince the windows guys of chef.
But unfortunately a chef-solo run produces 100% CPU usage.
The whole execution time is not really important to me (at the moment 12 seconds with the "getting-started" cookbook),
but what's critical is that the chef/ruby process eats up the whole cpu and therefore blocks the whole system.
I've disabled a few ohai plugins, but that doesn't change everything. Also it's not an disk I/O - problem , it's pure CPU usage.
I've tried to limit the cpu usage of the chef/ruby process to 50% (with Windows System Resource Manager), but no luck.
Is there any possibility to limit the cpu usage of the ruby process so that a chef-run doesn't block the whole system ? (i can't convince the windows guys of
chef if chef(or ruby) is blocking the whole system ...)
Windows Server 2008 R2 SP1 x64
1vCPU, 2GB RAM
Chef 10.14.2 (http://opscode.com/chef/install.msi)
