I often use more than 16 GB of RAM. Generally, I have 3-4 Windows 10 VMs running which each take at least 4GB to be stable. So if I have 4 running that is all the RAM already.
- ebg13 6y ago> 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."
- threeseed 6y agoThat'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.
- 0x53 6y agoHaha. 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.
- Jtsummers 6y agoI was running a Windows VM on my laptop earlier this year (before some of the telework issues got worked out). While, yes, you need at least 4GB/VM, by the time I had two running the issue wasn't RAM. Laptop CPUs just can't keep up with that workload IME. Not unless you get, maybe, the latest 16" MBP (if restricting ourselves to Apple's hardware).
- sercand 6y agoRunning 3-4 Windows 10 VMs is not a standart Macbook (at least not for 13" macbook) workload.
