    Curious as to why the Delphix Engine is showing a different CPU consumption than ESX? Check out VMWare and CPU Utilization Discrepancy Explained from our KB which explains the underlying reasons for this to occur, specifically in Delphix but also in other guests.

    Excerpt:
    "Individuals responsible for the administration and/or monitoring of systems using VMware and Delphix may have noticed that the guest VM associated with Delphix tends to show higher average CPU utilization than what would be considered normal when compared to a traditional application virtualized environment. Also, the performance metrics, specifically CPU utilization, reported by Delphix analytics may show a marked differential from those being reported by VMware tools like esxtop.

    This phenomenon is not unique to DelphixOS(DxOS). In fact, many guests with higher vCPU and memory requirements, will likely exhibit the same behavior. A number of papers have been authored on the subject* (see point 1 below), but here we are looking to identify why this occurs specifically for DxOS."
