I have 8GB RAM drive that has the temp folder on it.
I have my 8GB dev Ubuntu VM.
I use https://www.romexsoftware.com/en-us/primo-cache/ to speed up access to the 2TB Mechancial SATA disk. 8GB RAM, 120GB SSD - this is also where I run my VMs from and make sure to use clones when running labs for multi host deployments.
Chrome uses a lot of RAM
I run 3 Android BigNox.com VMs nealry all the time with 3GB RAM each.
So yeah, total 3,3,3,8,8,8 = 32GB usually in use/reserved 80% of the time. leaves me with 32GB to fire up games without stopping anything. Or spin up a bunch of VMs with zero slowdowns. Right now ProcExp says System has 48GB committed, 35GB Physical.
My current VM lab is running Docker deployments over the Multiple Datacentre scenario. Using https://bsdrp.net/ for the routers to simulate failures and see how things respond.
