Fixing Issues with Lightroom Running Slow.
If your like me and you’ve upgraded to Lightroom 4 or Lightroom 4.1 you might have noticed it running painfully slow at times. Happens to me all the time and I don’t know why. It’s inconsistent. I’ve hit the forums and Google and have decided to compile a list of every solution I’ve founded related to the issue. And I can tell you one thing, it’s not hardware related. I have these problems on the top of the line machines. 8-core solid state with 24 gigs of ram.
Here are a few tricks I’ve learned on How to Speed up Lightroom.
Make your folders smaller. The other day I imported about 500 photos from a days shoot. There was about a 7 second lag on any changes I made. I restarted my computer nothing worked so what I ended up doing was breaking that folder into two smaller ones. One with about 200 photos the other with closer to 300. Problem solved, Lightroom began performing fast again.
Increase your cache. I see people say this one a lot. I’ve never noticed it helping but maybe it will do something for some situations. Go into Lightroom and into your preferences. In file handling towards the bottom there is an option to increase your camera raw cache settings. Change it to like 5 or 10 GB. Also take this opportunity to purge your cache.
Change your Camera Raw compatibility. In your preferences under the file handling tab there is on option to change your camera raw compatibility. Try changing it to the latest camera raw. Or if you’re on the latest try rolling back to the previous. Not sure what this will do but I’ve seen people say to do this.
Trash your preferences. If you’re like me you’ve been updating your Lightroom software since Lightroom 2 across several different operating systems. Chances are things are messed up. This to me makes the most sense. I’m a Final Cut Pro editor and it’s very easy for the preferences to get messed up and tweak everything out little by little. So try deleting your Lightroom Preferences so it can write new ones. Just be sure to back them up onto your desktop first.
On mac they are located:
Your library will probably be hidden by default so to unhide it follow these steps. http://helpx.adobe.com/x-productkb/global/access-hidden-user-library-files.html
On windows it’s a little easier, the Preferences are located in this path: C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\Lightroom 4 Preferences.agprefs
You’ll lose your preferences but that’s a small price to pay for software that works.
Fix your disk permissions. If you’re on OSX your disk permissions could be messed up among other things. I use this program called Onyx. You can download it at http://www.macupdate.com/app/mac/11582/onyx
Run the verify and the cleaning. Or set up the Automator and do everything. This sometimes helps when you start noticing your computer just doing weird things.
A few more tricks to speed up Lightroom.
Optimize your Catalog. Do this by going into Lightroom. Select File -> Optimize Catalog. It will take a few minutes but will help speed up Lightroom browsing a bit.
Adjust your Preview Size. Do this by going into Lightroom. On a Mac click Lightroom go into Catalog Settings go to File Handeling. Now you can set your Standard Preview Size and Preview Quality to a lower setting to help your previews load a bit snappier. This will obviously effect your preview quality so adjust it to your taste.
Hope this was helpful. If you know of any other techniques for speeding up Lightroom or solutions to common issues with Lightroom running slow, send me a comment or Email and I’ll keep this updated as best as I can.
