Doing some research for a new CPS environment build and would like some real world feedback on whether someone is running CPS with oversubscribed/overcommited vCPUs.
Basically do you run 1:1 ratio or can you go 1:2 or 1:3 or more for the VMs?
Any performance impact?
Thank you.

On the database, jboss, rds we do not over subscribe those hosts (even 1:1 can cause lag due to core locking).. On lower volume servers (eprescribe for example) we have one host that is over subscribed about 3:1. Look up ready and costop if you are using vmware. The higher those go the more the users are affected.. Even if you arent over subscribing.

We do not oversubscribe DB/APP/Citrix servers. I am not currently oversubscribing on other servers but I have in the past without issue.
