so we finally found a quiet night to migrate our production environment
from chef server 10 to chef server 11.
we were previously running 10.16.2 on a dual core 8gb virtual machine,
serving about 450 VMs that each checked in every 15 minutes (with start
times randomized across the 15 minutes).
Over a 4 hour window, the VM would be severely stressed and we would
normally see between 2000 and 3000 timeouts and/or connection resets trying
to connect to the chef server, and chef runs that normally took around 25
seconds would take 5 minutes.
Over the same 4 hour window last night, there were zero timeouts, zero
connection resets, and the new chef 11 VM (same specs) was barely breaking
Oh yeah, and the average run time over all 450 vms went from 230 seconds to
I would call that a serious win and vote of confidence in the
Thanks guys for some amazing work!
