All done as you suggested but still Lightrooms performance is no better and it keeps crashing. Why don't you Adobe fix it and don't find workaround solutions that work ?
Many, many users have rolled back to LR CC 2015.1.1 / 6.1.1: http://www.lightroomqueen.com/how-do-i-roll-back-to-lightroom-2015-1-1-or-lightroom-6-1-1/ Wait until Adobe cleans up the mess with 2015.2 and get work done while others do the beta testing.
I've rolled back to 6.1.1 and I no longer have any crashing but performance is slow compared to Yosemite. Metadata writes taking ages, just seems slow, activity monitor show very little cpu load, and network traffic is low (I'm writing to a NAS)
Yes this helps the import process, but as far as I'm aware doesn't help with performance in any other area.
Just installed the latest El Capitan update (10.11.1) and it seems to have fixed the performance issues I was having, certainly with Lightroom 6.1.1 and it now seems. dare I say it, faster.
Now just wait for the new version of Lightroom to come out before upgrading again.
