Comment on Over engineering my homelab so I don't pay cloud providers

But my self hosted stuff doesn’t need particularly fast disk IO, so I don’t really notice even if there is a bottleneck lol

It definitely depends. If you use qcow2 files for your disks, they’re a copy-on-write format, which is slower than most file systems inherently. If the host system is also a copy-on-write file system, then it doubles your IO again.
If you’re using raw disks/partitions, there is minimal overhead that usually comes down to usually miniscule driver differences.

Yeah I’m running ZFS with raw disks, and most things are in containers anyways, just a few VMs for Windows or stuff that doesn’t like containers.
