updated to 6.0.1 (win7 x64) ... did not notice any speed issues.
it is as slow/fast as before.
A few more features of the update - I have lost all flags on flagged images and in one particular folder that had a dozen or so images in it there are only three images. Trying to Synchronize the folder shows 12 new images to import (that were there last night) but synchronizing pops up a dialogue stating no photos or videos were found to import. All of the images in the folder are showing in the Finder. Sigh...
Which MacOS are you on Mike?
Sorry for the trouble, I haven't noticed the slowdown on my system.
What if you reset Lr's preferences? blogs.adobe.com/lightroomjournal/2013/06/lightroom-basic-troubleshooting-to-fix-most-issu es.html#Preferences
Let us know how it goes.
Thanks for the insight Pete. For reference I'm on 10.10.3.
I tried one last step before resetting the preferences - I synchronized my entire library. Instead of only synching the "child" folder where the missing images should have been showing I synchronized my top most "patent" folder where all of my images are stored within. This brought back the missing images and LR is back to it's speedy self. I did lose the flags on the one directory but that is just 5 minutes of work. Thanks again for the resetting LR preferences idea. I'll keep that one.
