MacBook Air slow after High Sierra upgrade

Hi,

I have a mid-2013 MacBook Air, 1.7GHz Intel i7, 8GB RAM, 256GB SSD.

I upgraded to High Sierra and I started experiencing:

- slower boot

- 10/15 seconds to open apps (e.g. Office Word, etc)

- 5 seconds to get the capture cursor (shift-cmd-4), was immediate before, is immediate if I boot in safe mode

- 12 to 20+ mdworker processes. 0% CPU, but why are they alive?

Here is EtreCheck report, any help is appreciated

thanks

Stefano
