Could you please confirm which version of Lightroom are you using?
Which operating system : windows or mac?
Are you able to open that catalog directly?
If you are able to open it, would suggest you to optimize that catalog and test for its integrity.
Thank you for getting back to me so quickly!
Mac OS 10.11.2 working on a 2012 Macbook Pro
2.3 GHz Intel Core i7 16gb ram
Both catalogs open with no problem. Both catalogues optimized.
Still really slow...
I just let it run for an hour and there was only 75% progress.
Thanks for the update.
Go to Lightroom Preferences > File handling> increase the camera raw cache space to higher end (around 60-70GB) and then, check.
It also depends upon your previews quality.
If the preview quality is set to 1:1 or standard, that might cause the delay.
Ok, will increase the space when I get back to the office and give it a try.
I do have all previews set to 1:1 for faster editing of course but should probably go back and delete all older 1:1 that are 6+ months old.
Great tips...will update with results asap.
FYI...just got word that the cache was at 1gb...that could make a huge difference!!!...ok, will update soon.
That worked perfect! Thank you so much for the help!!!
Hope to chat again in the future!
All the very best,
