Very poor performance Mac OS host

All Linux VMs I've tried have exhibited this behavior (Kubuntu 14,16,18 and Fedora 2x)

Are all your VMs KDE based? That's pretty much the only difference I could see between your VM and mine. That, and the "Host I/O Cache" being enabled in mine, but that shouldn't matter too much, if any.

I'm going to try and I can replicate your "experience" with the KDE DVD. In the mean time, can you try a Gnome one and see what you get?

Yes - all the VMs I've tried have been KDE based. I'll try a Gnome distribution and report back. Thanks
