Ubuntu 20 VM Much slower than in ESXi

Hmmm. I kind of wonder what'd happen if you reinitialised your boot partition using the instructions here?

Thanks, I'll take a look at this later. Have to head off to do some other stuff just now.

can you run small 7zip single thread benchmark within your Ubuntu VM on ESXi then PVE ?
7zz b -mmt1

Not familiar with 7zz
Looking it up it looks like a zip utility

I spun up a new VM to test rather than using one imported form ESXi and performed the same test.
Same results. Seems as though Proxmox is significantly slower than ESXi on the same hardware.
I'm going to abandon this path at least for now.
