If you feel like your Lightroom is running as fast as it should (or it could), check out this article directly from Adobe which is all about how to optimize your settings, your hardware and software to make Lightroom run as efficiently as possible.

Here’s the link. 

The reason I’m sharing this is because I saw a number of questions this week asking things like “How much RAM should I be using?” and “What’s the optimum configuration for Photoshop or Lightroom?” during our KelbyOne members-only Webcast with Adobe’s own Worldwide Evangelist for Design and Photography, Terry White (It was Terry that pointed out this article from Adobe that goes though all the things you can do to make Lightroom run its best).

Hope you find that helpful. 🙂

Here’s wishing you a great weekend, and we’ll catch ya next week. 🙂

    For a lot of users a more appropriate topic would be “You Want Your Lightroom to Run?”
    The sunshine pump is working overtime at Adobe these days. If they put as much effort into engineering as they do marketing we could all enjoy life more.
    The latest release introduced the new “crash on import” feature, the “freeze while in develop module” add on, and the ever popular “print color correction” bonus!
    Seriously, the folks at Adobe have been horribly unresponsive this time around, and the “independent” Adobe champions have been silent.
    I’ve used Lightroom since its inception and this is the worst ever release.

    Since LRCC I have the following issue. I create 1:1 previews that take a very long time. If I do a few global corrections on the folder LRCC forgets all the previews and I have to make them again. This is very time consuming. What do I do?

      Make sure the Camera Raw cache is fairly large. (Edit – Preferences – File Handling … in the English PC version). Apparently, they keep some of the initial work on demosaicing of raw sensor data in there (maybe more…) , and if you need new preview creation that’s a step they wouldn’t need to re-do and it might help reduce the slowdown on large number of files. I have that ACR cache at 70GB.

    Really…. i’m supposed to enjoy an adobe post that predates lightroom 5 and 6 and does not even reference Windows 10? So there is nothing new to add for the latest versions of LR? And nothing new for the latest OS options?

    Scott, i think you need to tell your friends at Adobe that such a document should always reflect the latest versions of both their software and the operating systems that are current.
    Frankly i am quite disappointed that this would be considered new information when the post is clearly several year old!

    Sadly due to the memory leak my solution to speeding up light room is close it every 30m and reopen : P
    Or run it on my mac

    Not exactly up to date though, Adobe. “In the Finder, navigate to the Applications folder and click Adobe Lightroom 3.”!

      It seems that the latest releases are really slowing down. I wish Adobe would take time off from new features for just one release and concentrate ALL of their efforts on optimizing the performance. There are new raw processors on (or coming onto) the market that I think people will seriously consider if they can’t get the performance out of Lightroom that they need.

      My own system is fairly fast (including a 1TB SSD for images and a 500Gb SSD for catalog and previews) with 16Gb of memory and it just keeps getting slower.

      Come on Adobe, make performance a priority! The product you purchased (to make Lightroom) was known for it’s speed (RawShooter Pro, which I was using before Adobe came out with LR). It started fast … there are lots of bells and whistles today that RSP never dreamed of, but I do think we can still get back some of the performance we’ve lost with a bit of effort put into optimizations.

        I can’t agree more… many of us have been complaining about the lag in performance we are experiencing. I’m sitting here with an i7 iMac 27″ with 32GB of memory and although the 3Tb fusion drive isn’t the best, LR used to perform better than it does now. It used to boot up fast (ver 5.7 and earlier) but now in ver’s 6-6.6 it’s quite slow.

      Also no mention of SSD drives if you have the option.
      Catalog related files on the SSD helps substantially, also if writing xmp files.
      1:1 previews can kill import speed, if you care about that phase and can defer it.
      If you pop to PS regularly, leave it up when you save (then close) out your files back to LR – you save the executable load, run, plugins etc. time.
