What are the actual performance characteristics of the vCPUs? I had a farily awful experience at my last job... My 4 cpu virtual desktop was virtualbox emulating a xeon form 2010 w/16gb of RAM. Loaded with monitoring software. Barely useable. No 3d accelleration. It choked whenever I tried to run high end software like, well, Figma.
