2016-1 was reasonably faster with bigger files, but after 2016-2 memorycounts of 70 GB, 99,8% cpu and supersloooow sketchup is back. What went wrong and how to remedy this? Anyone ideas?

@Devin,

I onderstand the problems, but still feel greatly distrusted. And using a hub would add to the cluster behind my mbo with thunderbolt screen again. It again adds to complexity. See Vectorworks, who have tackeled the licensing issue very effectively in the software since 2009. Adobe let you install on two machines, when not used at the same time. Until they started the rip-you-off-monthly scheme of CC. I seriously think dongles sooo 1995. There must be better ways to support the user. It lacks creativity.
And yes, autocad is hacked, but at those horrific prices you almost write an open invitation, for otherwise you need a mortgage. I won't hack, but somewhere some understanding pops up.

I love V-ray for its quality, but I am stuck with 1.49 because of the dongle. On my mb retina I only have the ports, which are accupied with back-up and other neccessities.
Why is it Chaos has such a distrust in me it wants me to BUY a dongle? Why would we want to use a product from a supplier who really thinks we all will steal a free ride? What kind of we-dont-want-your-business mentality is this? I feel treated like a potential criminal when I see this on the website.
Why is this your way of licensing?
