Ok, thanks nthorst for changelog. (BTW, where they are?)

Installed 088 driver and indeed in Ubuntu 14.04 LTS speeds goes up tenfold.
vSphere client however still doesn't work fast - ~100-150Mbps from SSD datastore to desktop SSD.

Also problem is still when I copy from one VM to another (Ubuntu<->Win10) on the same SSD. Speed often fall below 1 MB/s and even freezes for some time.

I decided to try Hyper-V. I also have large HDDs and could stuck in 2 TB limit with esxi.

Thanks again

A
