PI on Hyper-V Ubuntu way slower than Win 10
« on: 2018 June 26 10:11:00 »
I finally figured all the installation and file issues in installing PI in an Ubuntu VM on my Win 10 PC, but when I run benchmark I get about 50% higher swap speed (great) but only 25% of the Windows CPU speed (~6K to ~1.5K).  I must have set up something wrong, but I have no idea what to tweak.  Any advice would be appreciated.

The PC is a 4770K OC'd to 4.4gHz with 32Gb Ram and ~7TB of SSDs and HDDs.  I use a 16gb Ramdrive with 4 swap files for PI.

The VM was set up with 8 logical cores, 16Gb ram allocated, and a 32GB swap disk and 30Gb OS partition on a Samsung 850 SSD shared with various files (mostly photos) but not my Windows boot drive).  I've not set up anything else in Hyper-V or in Ubuntu.   

Any suggestion on what I either did wrong or need to tweak?
