I downloaded the latest version of Lightroom on Friday October 9th 2015 and since then have had huge difficulty using Lightroom. The whole system is incredibly slow, my battery is eaten away when using Lightroom and its difficult to import images.
Many of us recommend that you revert to CC 2015.1.1 / 6.1.1: How do I roll back to Lightroom 2015.1.1 or Lightroom 6.1.1?. Wait until Adobe cleans up the mess with CC 2015.2 and 2015.2.1, and let others do the beta testing.
Re the new import, please add your vote and detailed opinion to this topic in the official Adobe feedback forum: http://feedback.photoshop.com/photoshop_family/topics/new-update-6-2
