As far as I'm aware, iCloud is NOT a kernel-level technology. OS X talks to iCloud when you choose to save things to iCloud / iCloud Drive (the contents of which are cached locally in a specific location). Otherwise it does not use iCloud.

It's entirely possible that something else I/O-related has changed in Yosemite that is having an impact. For instance, the boot volume is converted to a Core Storage logical volume on upgrade.

We still don't know what (if anything) is causing the issue. Craig's experience on Snow Leopard makes me think that it may not be a system-level thing.
