The guests are running Citrix so a lot of the traffic is going to be logons, openning applications and normal business use. Nothing too crazy.

I inherited this environment about 6 or 8 weeks ago, so I can't really tell you all the reasons they chose to go with 4 vCPU on all the guests. I was told that's where they saw the best performance benchmarking during the architecture part. Unfortunately, that was long before my employment here so I haven't seen any of that.

In any case, I would also agree that starting with 1 or 2 vCPUs and moving higher based on need is best practice and one I would use if I was architecting.

Really was trying to make sure my logic was sound before I make suggestions on a fix. To date, users really don't have any issues related to performance on an ongoing basis. This is more of something I just noticed as I have been learning the environment and thought it might be a small win or minor change that could be made to make sure the environment is stable. And I don't like seeing all that orange mudding up my perf graphs.
