PureOS as Proxmox guest

Hello!

Trying to install PureOS 9.0 in Proxmox. Is there any recommendation for the setup? I’ve tried with 2 CPU (type default and host too), 4 GB of RAM as other linux distros, but PureOS seems a bit laggy to me. So if anyone has any recommendation, like numer and type of CPU cores, size of the RAM or any other, i’d thank it.

Thanks any help you can provide!
