Instant Clones - High CPU/ Memory Usage

[AGIS]

I have multiple Horizon view 7.3.2 Environments. Backend vcenter is 6.0.0 7924804 appliance in one environment and the other is 6.5.8815520.  In all of our Instant Clone pools instances, they consume a ridiculous amount of cpu and memory.

Does anyone have any insight as to what the fix for this is? These instant clones are both Windows 10 and Windows 7.

We are really at a loss as this was sold as a pretty awesome feature but has created some utilization headaches.

Have you done any analysis to determine what processes are consuming the memory and CPU?

Like was said before how are you determining this. If I look at the cp-parent vms on mine I see they all use about 1-2mz and about 300mb a piece.

and then each of the clones use as much as I would expect. I'm curious to see if you did a pre instant clone check and a post instant clone check to and noticed a increase while still serving the same number of VMs. I created our new environment to be 100% instant clone from the beginning so I wasn't able to do that type of research. From what I've seen the memory being used on each of our hosts is expected.

The alarms are not accurate by the way, and I think if you upgrade complety to 6.7 the alarms for the cp-parent vms go away.

nah, i just deployed horizon 7.5 instant clones with latest vcenter 6.7 and esxi 6.7 fully patched and they are still there.

There's a KB article which mentions your exact problem. Apparently it is a false alarm and as of when the KB article was created, there's no workaround at the moment. They just said to ignore it. Here's the link below:
