SU2016 select all freeze

I’m working on quite a big model with 20+ layers all divided into groups and components. I’m on OS X El Capitan. When I’m selecting the whole model for geo-locating it it is super slow and eventually unresponsive. I feel this is way better in SU2015. What happened guys? I can’t geo-locate my model with precision now. I feel that it’s not a viewport render problem really, orbiting and zooming works OK but when the whole model is selected by right-, left- or Cmd+A-selection it can’t be rotated or moved. Sketchup freezes and I have to force quit it.

The over all handling of a large models seems slower in SU2016 compared to SU20015. There is some serious lag in the viewport.
