It looks much better now, not sure how I missed that, I have it in loader.conf
on my older T430...

$ truss -c cp -r /usr/src/sys sys
...

                        2.654507712  253161   28445

# diskinfo -tv /dev/nvd0p3.eli
Transfer rates:

        middle:        102400 kbytes in   0.101418 sec =  1009683 kbytes/sec
        inside:        102400 kbytes in   0.102737 sec =   996720 kbytes/sec

Geom name: nvd0p3.eli

I think those numbers are more than acceptable, right? 

Thanks for your support!
