[SOLVED] Hyper-Threading vs No Hyper-Threading; Fixed vs Variable Memory

[Carlos Estrada]

Hi. I have a question for Proxmox 4.4.

There is the option "Ballooning" which is available with the option "Use fixed size memory". In the help manual says :

Even when using a fixed memory size, the ballooning device gets added to the VM, because it delivers useful information such as how much memory the guest really uses. In general, you should leave ballooning enabled, but if you want to disable it (e.g. for debugging purposes), simply uncheck Ballooning.

I'm configuring a Windows server 2012 VM. I want to have a fixed size memmory, but I'm confused about this option. Should I enable it?

This Wiki Article suggests that the Ballooning driver is a source of performance problems.

Is this still the case on Proxmox 7?

I have the ballooning driver active on all 15 Windows VMs and I didn't notice any performance issues.

Yup, it links here so I figured an update can't hurt.
