Question

Lightroom CC 2015 running slow

Hi guys

I have only upgraded to CC 2015 some days ago, and I'm having troubles with slow response in the Develop mode. For example, when I drag the exposure slide to the left, it lags for a second and then it works. I didn't have this in the previous LR version. It's kind of annoying because when editing down 600 photos, I really feel the extra time. It's taking me double as long now to edit these pictures.

I have an iMac with 8GB RAM and a 3.06Ghz processor. My photos are stacked on a seperate external hard drive with USB3. My catalogue is on the computer.

I've tried turning of the GPU accelarator, but nothing changes. I've also tried freeing up space on my drives, but that doesn't change anything either.

Does anyone have any ideas?

Many thanks!

    I found out that all the photos that we're going extremely slow had noise reduction on them. I just disabled noise reduction on all of my photos I'm editing, and this increases speed significantly. As a work-around, I can add noise reduction at the end of the process, but still, I should not supposed to be doing this. With this is mind, does anyone know what might be the problem behind this?

    It could be of value to try the Lightroom Classic CC upgrade. The main feature of this upgrade is speed. When you upgrade, be sure that the "remove old versions" is switched off to return easily to your prior version if this does not solve your problem. Please note also that you should check the minimum requirements before installing (even that I think, that the creative cloud app does not propose Lr Classic, when the specs of the computer do not support it).

    Lr Classic CC is the successor of Lightroom CC 2015.X. Lightroom CC (the new one) is a new application, that stores your images in the cloud. Functionality between both flavours of Lr are not the same. More info is found on the Adobe web site: Introducing: Lightroom CC, Lightroom Classic CC and More | Photoshop Blog by Adobe .

    Thanks for the advice Abambo. I just upgraded to Lightroom Classic CC, but unfortunately the problem persists. It still takes 2-3 seconds to perform any adjustment. I'm a bit clueless... I don't know if I have to look at my iMac or my external hard drive. I thought it was because the files I'm working with are on an external drive with USB2.0 connection, but some forum users have said here that wouldn't cause the slowness. What else could be it?

    Sorry for the long silence! I was on holiday for a couple of weeks. Back to work right now and I'm still having these issues with Lightroom CC. I reduced brushing to a minimum, because using (especially healing) brushes goes incredibly slow. Photos taken outside in daylight go significantly faster than photos taken inside in tungsten light, though it all goes quite slow compared to when I had Lightroom 5.5.

    Please follow those recommendations: Optimize Lightroom performance .

    Adobe is aware that there are some performance problems, as they did a survey on this in July. I excpect one of the next updates to address those problems.

    (and to answer that question too: I have no idea, when this will be, as Adobe did not make yet an announcement)

    Thanks! I guess I need to upgrade my iMac. I'm working with raw files which are on a seperate external hard drive. My iMac has only USB 2.0 ports, which are too slow for Lightroom CC 2015.
