    Lightroom Performance

    Trevor Lee

      I am using a 2 year old iMac with a library of about 160,000 images and make extensive use of keywords / metadata.  While the main images are on a NAS, the catalogue is local.  I wanted to be able to manage my whole catalogue within Lightroom so can select all images with a particular keyword for example.

       

      Performace has degraded to the point that it takes over 8 hours to download a single 64GB memory card and even longer if the I add keywords at this point.  Memory use seems OK but CPU sits well in excess of 100%, typically 120-140% and stays there consistently. When using Lightroom the transition from one image to the next can be slow, as is the rendering of the image which brings a pretty poor experience and buckets of frustration.

       

      It would be a great shame to have to split the catalogue as it will ruin my workflow.

       

      Is anyone else experiencing the same issues and does anyone know of a magic solution.

          Usually, slowdown like this has nothing to do with catalog size. This is an extremely common misperception. If I was to make a list of the top ten things that could cause slowdowns like this, catalog size is not on the list.

           

          Could you please state the exact version NUMBER of Lightroom that you have (please don't tell me it is up to date or that you have the latest version). Also please state your operating system.

           

          Also please provide this information:

          • Make and model of CPU
          • Free space on the hard disk with the photos
          • Free space on the hard disk with the catalogs
          • Amount of memory
          • Size in megapixels (not megabytes) of the photos you are importing, and how many of these photos are on the 64GB card you are importing
          • GPU acceleration on or off

              The first thing I would try is turning off the GPU acceleration.
