What is the measure in vSphere if VM is over spec or causing other VMs to slow down ?

Hi All,

How to detect or get some evident if the one big VM is too large to be running as a Virtual Machine ?

I've got one VM:

vCPU 16x
vRAM 112 GB
C:\ 400 GB - Thin Provision

The ESXi that I run is like below:

I need to proof and show some evidence to the management team that if this big VM is too big to be virtualized or it can be good candidate to be splitted into two VMs instead.

Thanks.

In general true VMs will always run slow.

If your VMs are running Linux, switching to LXD solves all manner of performance problems.

For non-Linux OSes, I've found VirtualBox tends to be one of the fastest VM systems.

@David you are trying to compare a type 1 Hypervisor (ESXI/Hyper-V) to a Type 2 Hypervisor (Virtual Box, Vmware Workstation, LXD), which is comparing apples to oranges

Hi All,

This is Windows OS and the screenshot that I posted is the specs of one of the ESXi hosts out of 4 in total.
