About 6 months ago I upgraded my desktop from 16 to 48 gigs cause there were a few times I felt like I needed a bigger tmpfs.
Anyway, the other day I set up a simulation of this cluster I'm configuring, just kept piling up virtual machines without looking cause I knew I had all the ram I could need for them. Eventually I got curious and checked my usage, I had just only reached 16 gigs.
I think basically the only time I use more that the 16 gigs I had is when I fire up my GPU passthrough windows VM that I use for games, which isn't your typical usage.
Wouldn't it have been easier and more effective to just make them coal shaped?
