How much RAM is the sweet spot for development VMs?

32GB is the sweet spot for dev VMs. Going from 16GB to 32GB is the single best upgrade because with 16GB you’re constantly fighting the host OS for memory. With 32GB, you can give a VM 12-16GB comfortably while the host still has plenty of room for your browser, IDE, and Slack. 64GB is rarely needed unless you’re running three heavyweight VMs or doing Windows development on a Mac.
