> Generally, I have 3-4 Windows 10 VMs running

What are you doing that needs them all actually running simultaneously? Disk-backed VM pause/resume is extremely fast when your SSD's sequential read/write performance is measured in GBps.

I have a hard time imagining a workflow that actually uses multiple systems all at once, so to me what you're saying sounds like "Well of course my RAM gets filled if I fill it on purpose."

That's assuming that your SSD is doing nothing else at the time that it is pausing/resuming.

Often it is. And so whilst SSDs are fast they still aren't fast enough to not slow everything else doing under high load.

Haha. I will admit that it is sometimes just for convenience, but when testing networking code, or writing things to interoperate with large system I do really need 3-4 VMs running.
