Containers are way too slow, and take too much space (they don’t share dependencies). Also doesn’t necessarily play well with tools AND is hard to setup for dev environments (what do you mount?)

Containers run nearly identical to native performance and best VMs in practically every category.

In what way are they slow?

On my mac it’s really slow to use docker. Maybe I should increase the ram it uses

Docker containers run in a VM on Mac.

I don't use Apple products so I can't help you there. I assume it's doing some networking madness to expose a Linux VM through a bridge or something similar.
